by Paul Hegarty.......... "Full with Noise,..." is about noise music, specifically the version that has come to be called Japanese Noise -- itself composed of many different strands. The first half deals with the question of noise. What is it, whose is it, and how can we think about it. Also, how does noise inflect our thinking, rather than being an object; at what point does noise lose its noiseness and become meaning, music, signification? Or -- is there even a point where noise can subsist? Mostly, the text below takes the view that noise is a function of not-noise, itself a function of not being noise. Noise is no more original than music or meaning, and yet its position is to indicate the banished, overcome primordiality, and cannot lose this 'meaning'. Noise, then, is neither the outside of language nor music, nor is it simply categorisable, at some point or other, as belonging exclusively to the world of meaning, understanding, truth and knowledge.

Dirty HC Punk explosion - Bristol scene Rise up + Disorder 9 free CDs
From The Cortinas to Lunatic Fringe and Disorder, Bristol had a huge Punk scene that has influenced, affected and stimulated a vast range of artists that operate in the city. Many of these artists produce music that wouldn’t necessarily suggest a Punk heritage but scratch beneath the surface of a lot of the major players in the Bristol milieu and you will find a fondness for the times of `spikey barnets’, limited musical ability, a `F*** You’ attitude and disrespect for the music industry and its poseur hierarchy.

A straight shot west out of Boston on I-90 will carry you, in two hours or less, to Western Massachusetts, where the country still looks like it did twenty or even 40 years ago: college towns, I-91 tracing the same lazy ladder from Springfield up through Holyoke and Northampton, Amherst and Deerfield. Out there it's taken for granted that the houses will be drafty, the winters uniformly long, and that, on any given trip to the local supermarket, one might spot Thurston or Lou or Kim or J, on-and-off locals for more than twenty years. {audio}http://www.archive.org/download/DinosaurJrDrawings/07Drawerings_64kb.mp3{/audio} ...

By way of decrying a society that left its citizens unbearably restrained, Edith Wharton describes how in New York in the 1870s, women would order dresses from their Paris dressmakers and then leave them in tissue paper at least two years before wearing them in public; the thought of showing them "in advance of the fashion" was unforgivably vulgar. Social life has changed, but cultural life seems just as restricted now – even Animal Collective are held back by trends that seem a couple of years old (and that they helped to invent). When I think back on 2009, I’ll first remember how our impoverished aesthetic generation repeatedly scraped the resin from the cultural trash barrel. Every second person is wearing neon leggings, and the ones who aren’t rock a ‘70s aesthetic, with high-waisted jeans and moccasins. Christmas sweaters are getting impossible to find at the thrift store. Ska revival. Garage rock revival. It never ends. Read More ...
Black Punk Time: Blacks in Punk, New Wave and Hardcore 1976-1984 + free albums
By James Porter and Jake Austen ....... When punk-rock arrived--as we now know it--back in 1975-77, it was the kick in the ass the music world needed. At a time when the wide-ranging rock scene incorporated everything from Midwestern Metal to Outlaw Country to funk-fusion combos like Weather Report, there was an overall, evident energy drop. When the debut albums appeared from the Ramones, the Dictators, Patti Smith, the Sex Pistols, the Dead Boys, and others, the edge was back. As Spin, VH1, Rolling Stone and the rest of the self-important "Rock History Reports" so boldly declare these days, punk was the wildest, angriest, most vital, most energetic, hottest shit going.

For a small country New Zealand has long been pumping out some impressive music. Way back in the 1960s it was crazed long-haired punkers messed up on all sorts of stuff - musical (the Pretty Things, Love, the 13th Floor Elevators, the Troggs and who-knows-what-else) and I guess otherwise. Some of the best of these bands (at least, the ones that recorded) can be heard on Wild Things vol 1 and 2, compiled by NZ music historian John Baker, the first of which came out on Flying Nun, the second probably on Baker's own Zero Records, also the home to No. 8 Wire: Psychedelia Without Drugs.

Leon Theremin /1896-1993/ - the great forefather of Rock N' Roll /big noise master/
In 1919, in the midst of the Russian Civil War, Theremin invented the musical instrument that bears his name. The theremin is an electronic device that resonates sound when its operator waves his hands near its two antennas. It was the first musical instrument designed to be played without being touched. He invented the theremin (also called the thereminvox) in 1919, when his country was in the midst of the Russian Civil War. After a lengthy tour of Europe, during which he demonstrated his invention to full audiences, Theremin found his way to the United States. He performed the theremin with the New York Philharmonic in 1928. He patented his invention in 1929 (U.S. Patent 1,661,058 ) and subsequently granted commercial production rights to RCA. In 1938 Theremin was kidnapped in the New York apartment he shared with his American wife (the black ballet dancer, Iavana Williams) by the NKVD (forerunners of the KGB). He was transported back to Russia, and accused of propagating anti-Soviet propaganda by Stalin. Read More ...
For just over 10 years, London's Guapo has been working in the world of avant and progressive rock. The band's past is a bit hard to track with its numerous lineup changes and guest musicians. The most recent change in roster was the resignation of Matthew Thompson, the founding member of Guapo, which occurred just before the release of 2005's Black Oni. The departure of Thompson has left Guapo with percussionist David Smith and multi-instrumentalist Daniel O'Sullivan. Though O'Sullivan is by no means a founding member of the band, but he was essential in honing the sound on Guapo's last two LPs: Five Suns and Black Oni. These two albums have been pivotal in building Guapo's following of fans, so it's hard not to credit O'Sullivan as an asset to the band.... {audio}http://www.neurotrecordings.com/artists/guapo/audio/Guapo-The%20Selenotrope.mp3 {/audio} ...

Cyberwar Hype Intended to Destroy the Open Internet
The biggest threat to the open internet is not Chinese government hackers or greedy anti-net-neutrality ISPs, it’s Michael McConnell, the former director of national intelligence. McConnell’s not dangerous because he knows anything about SQL injection hacks, but because he knows about social engineering. He’s the nice-seeming guy who’s willing and able to use fear-mongering to manipulate the federal bureaucracy for his own ends, while coming off like a straight shooter to those who are not in the know. When he was head of the country’s national intelligence, he scared President Bush with visions of e-doom, prompting the president to sign a comprehensive secret order that unleashed tens of billions of dollars into the military’s black budget so they could start making firewalls and building malware into military equipment.

The Peyote Way Church of God - believe that the Holy Sacrament Peyote can lead an individual toward a more spiritual life
The Peyote Way Church of God is a non-sectarian, multicultural, experiential, Peyotist organization located in southeastern Arizona, in the remote Aravaipa wilderness. It is not affiliated with the Church of Jesus Christ of Latter Day Saints, the Native American Church, or any other religious organizations, though we do accept people from all faiths. Church membership is open to all races. We encourage individuals to create their own rituals as they become acquainted with the great mystery. We believe that the Holy Sacrament Peyote, when taken according to our sacramental procedure and combined with a holistic lifestyle (see Word of Wisdom), can lead an individual toward a more spiritual life. Peyote is currently listed as a controlled substance and its religious use is protected by Federal law only for Native American members of the Native American Church. Read More ...
Japan’s Annual Penis Festival – Celebrates Fertility
KOMAKI, Japan — It's springtime in Japan and that means one thing. Actually, two things. Penis festivals and vagina festivals. It may sound like a sophomoric gag. But these are folk rites going back at least 1,500 years, into Japan's agricultural past. They're held to ensure a good harvest and promote baby-making. Maybe they should hold more such festivals. Japan has one of the world's lowest birthrates (1.37 children per woman), which experts blame on stagnant incomes and changing gender relations. Read More ...
Dreamachine - stroboscopic flicker device enter you to a hypnagogic state - try it right here in your browser
The dreamachine (or dream machine) is a stroboscopic flicker device that produces visual stimuli. Artist Brion Gysin and William Burroughs's "systems adviser" Ian Sommerville created the dreamachine after reading William Grey Walter's book, The Living Brain. In its original form, a dreamachine is made from a cylinder with slits cut in the sides. The cylinder is placed on a record turntable and rotated at 78 or 45 revolutions per minute. A light bulb is suspended in the center of the cylinder and the rotation speed allows the light to come out from the holes at a constant frequency of between 8 and 13 pulses per second. This frequency range corresponds to alpha waves, electrical oscillations normally present in the human brain while relaxing. Read More ...

Island of Ghosts: Hashima Island - Japan’s rotting metropolis
Hashima, an island located in Nagasaki Bay, is better known as Warship Island (Gunkanshima). The island was inhabited until the end of the 19th century, when it was discovered that the ground below it held tons of coal. The island soon became a center of a major mining complex owned by Mitsubishi Corporation. As the complex expanded, rock brought out of the shafts was used to artificially expand the island. Seawalls created in this expansion turned Hashima into the monstrous looking Gunkanshima; its artificial appearance makes it looks more like a battleship than an island. Read More ...
The Marijuana Conspiracy - The Real Reason Hemp is Illegal
MARIJUANA is DANGEROUS. Pot is NOT harmful to the human body or mind. Marijuana does NOT pose a threat to the general public. Marijuana is very much a danger to the oil companies, alcohol, tobacco industries and a large number of chemical corporations. Various big businesses, with plenty of dollars and influence, have suppressed the truth from the people. The truth is if marijuana was utilized for its vast array of commercial products, it would create an industrial atomic bomb! Entrepreneurs have not been educated on the product potential of pot. The super rich have conspired to spread misinformation about an extremely versatile plant that, if used properly, would ruin their companies. Read More ...

Not so long ago experts predicted the imminent collapse of religion in modern western culture. Religion – often synonymous in these discussions with superstition, magic, and delusion – would at last give way to the autonomy of human reason and the power of the experimental method of natural investigation. But something happened on the way to religion’s funeral. People kept on believing. Recent neuroscientific and evolutionary research has suggested that either many of the hallmarks of religion are, or are byproducts of, adaptations that helped our earliest ancestors survive.

Freegan - strategies for sustainable living beyond capitalism
Freegans are people who employ alternative strategies for living based on limited participation in the conventional economy and minimal consumption of resources. Freegans embrace community, generosity, social concern, freedom, cooperation, and sharing in opposition to a society based on materialism, moral apathy, competition, conformity, and greed. After years of trying to boycott products from unethical corporations responsible for human rights violations, environmental destruction, and animal abuse, many of us found that no matter what we bought we ended up supporting something deplorable. We came to realize that the problem isn’t just a few bad corporations but the entire system itself. Read More ...
A temple complex in Turkey that predates even the pyramids is rewriting the story of human evolution. They call it potbelly hill, after the soft, round contour of this final lookout in southeastern Turkey. To the north are forested mountains. East of the hill lies the biblical plain of Harran, and to the south is the Syrian border, visible 20 miles away, pointing toward the ancient lands of Mesopotamia and the Fertile Crescent, the region that gave rise to human civilization. And under our feet, according to archeologist Klaus Schmidt, are the stones that mark the spot—the exact spot—where humans began that ascent. Read More ...
Learn How to Pronounce the Iceland Volcano Eyjafjallajokull and remember; When He Erupted In 1821, it lasted 2 years
The last time Eyjafjallajökull erupted, it lasted 2 years stretching from 1821-1823. It also erupted in 920 and 1612. Eyjafjallajökull's eruption usually precedes an eruption for another Icelandic volcano called Katla, as it did in 1823. Katla's eruptions are usually more violent than Eyjafjallajökul's. Due to the second activity on Eyjafjallajökull volcano since April 14, there are thousands of flights have been cancelled not only in Europe but also some flights from Asia, America and other continents. More over, it was also reportedly more than ten thousands of air travelers still stranded after a plume of ash cloud spreading across thousands of miles. No need to repeat the same news in every single post, actually there’s an interesting thing from the Iceland volcano’s name Eyjafjallajokull. Pronunciation is so difficult for some of us. Even, many people still don’t know what’s the right pronunciation of Eyjafjallajokull volcano. Did you know that? Read More ...
A speech given by Bertrand Russell, March 6, 1927, National Secular Society, South London branch, Battersea Town Hall ............ "As your chairman has told you, the subject about which I am to speak tonight is "Why I Am Not a Christian." Perhaps it would be as well, first of all, to try to make out what one means by the word "Christian." It is used these days in a very loose sense by a great many people. Some people mean no more by it than a person who attempts to live a good life. In that sense I suppose there would be Christians of all sects and creeds; but I do not think that is the proper sense of the word, if only because it would imply that all the people who are not Christians -- all the Buddhists, Confucians, Mohammedans, and so on -- are not trying to live a good life. I do not mean by a Christian any person who tries to live decently according to his lights. Read More ...
Victorian England popular&legal drugs (hashish, opium, absinthe and Chloral)
Victorian England, spanning roughly the reign of Queen Victoria (1837-1901), is characterized in popular understanding as a time of personal and family values. The codification of the notion of values developed into specific and detailed ideas about social and cultural propriety and restraint. The very term "Victorian" has come to be used in our own time by cultural conservatives who look to the reign of Victoria as a touchstone for their own desires about social order. Prudishness, excessive formality, and repression, it is popularly assumed, characterized Victorian culture. Read More ...
The World's First Commercial Brain-Computer Interface + history of BCI
A brain–computer interface (BCI), sometimes called a direct neural interface or a brain–machine interface, is a direct communication pathway between a brain and an external device. BCIs are often aimed at assisting, augmenting or repairing human cognitive or sensory-motor functions. Research on BCIs began in the 1970s at the University of California Los Angeles (UCLA) under a grant from the National Science Foundation, followed by a contract from DARPA. The papers published after this research also mark the first appearance of the expression brain–computer interface in scientific literature. Read More ...
The giant ALICE detector is already underway at CERN, and researchers are scrambling to add an electromagnetic calorimeter to capture jet-quenching, the newest way to look inside the quark-gluon plasma — the hot, dense state of matter that filled the earliest universe, which the Large Hadron Collider will soon recreate by slamming lead nuclei into one another. CERN's Large Hadron Collider (LHC) is known mainly as the accelerator that will soon begin searching for the Higgs particle, and other new physics, in proton collisions at unprecedented energies — up to 14 TeV (14 trillion electron volts) at the center of mass — and with unprecedented beam intensities. But the same machine will also collide massive nuclei, specifically lead ions, to energies never achieved before in the laboratory. Read More ...
The Secrets of Coral Castle and pyramids EXPLAINED by Leedskalnin's Magnetic Current theory
Coral Castle doesn't look much like a castle, but that hasn't discouraged generations of tourists from wanting to see it. That's because it was built by one man, Ed Leedskalnin, a Latvian immigrant who single-handedly and mysteriously excavated, carved, and erected over 2.2 million pounds of coral rock to build this place, even though he stood only five feet tall and weighed a mere 100 pounds. Ed was as secretive as he was misguided. He never told anyone how he carved and set into place the walls, gates, monoliths, and moon crescents that make up much of his Castle. Some of these blocks weigh as much as 30 tons. Ed often worked at night, by lantern light, so that no one could see him. He used only tools that he fashioned himself from wrecks in an auto junkyard.

Microbial communities in fluid inclusions and long-term survival in halite + The 11th Hour - documentary
Fluid inclusions in modern and ancient buried halite from Death Valley and Saline Valley, California, USA, contain an ecosystem of “salt-loving” (halophilic) prokaryotes and eukaryotes, some of which are alive. Prokaryotes may survive inside fluid inclusions for tens of thousands of years using carbon and other metabolites supplied by the trapped microbial community, most notably the single-celled alga Dunaliella, an important primary producer in hypersaline systems. Deeper understanding of the long-term survival of prokaryotes in fluid inclusions will complement studies that further explore microbial life on Earth and elsewhere in the solar system, where materials that potentially harbor microorganisms are millions and even billions of years old.

According to the article, some American and British scientists working in Antarctica on January 27, 1995, noticed a spinning gray fog in the sky over the pole. U. S. physicist Mariann McLein said at first they believed it to be some kind of sandstorm. But after a while they noticed that the fog did not change its form and did not move so they decided to investigate. Read More ...
How Norbert Wiener Invents Cybernetics + his book " God and Golem, Inc.........."
Norbert Wiener invented the field of cybernetics, inspiring a generation of scientists to think of computer technology as a means to extend human capabilities. Norbert Wiener was born on November 26, 1894, and received his Ph.D. in Mathematics from Harvard University at the age of 18 for a thesis on mathematical logic ( see below "The Logic of Boolean Algebra"). After working as a journalist, university teacher, engineer, and writer, Wiener he was hired by MIT in 1919, coincidentally the same year as Vannevar Bush. In 1933, Wiener won the Bôcher Prize for his brilliant work on Tauberian theorems and generalized harmonic analysis. Read More ...
Seven theories of everything that pretend to describe the fundamental nature of the universe
We still don't have a theory that describes the fundamental nature of the universe, but there are plenty of candidates.
The "theory of everything" is one of the most cherished dreams of science. If it is ever discovered, it will describe the workings of the universe at the most fundamental level and thus encompass our entire understanding of nature. It would also answer such enduring puzzles as what dark matter is, the reason time flows in only one direction and how gravity works. Small wonder that Stephen Hawking famously said that such a theory would be "the ultimate triumph of human reason – for then we should know the mind of God". But theologians needn't lose too much sleep just yet. Despite decades of effort, progress has been slow. Rather than one or two rival theories whose merits can be judged against the evidence, there is a profusion of candidates and precious few clues as to which (if any) might turn out to be correct.

A million pound detector has been built at the University of Warwick as part of a vital experiment to investigate fundamental particles - neutrinos. Read More ...
It was nearly the end of WWII. At that same time, scientist Viktor Schauberger worked on a secret project. Johannes Kepler, whose ideas Schauberger followed, had knowledge of the secret teachings of Pythagoras that had been adopted and kept secret. It was the knowledge of Implosion (in this case the utilization of the potential of the inner worlds in the outer world). Hitler knew - as did the Thule and Vril people - that the divine principle was always constructive. A technology however that is based on explosion and therefore is destructive runs against the divine principle. Thus they wanted to create a technology based on Implosion. Read More ...
The Size Of Our World or How Insignificant the Earth Really Is in the Universe
Compared to you and me, the Earth is really big. But compared to Jupiter and the Sun, the Earth is pretty tiny. There are many ways we can measure the size of the Earth. Let's look at how big the Earth is, and then compare it to other objects in the Solar System. The diameter of the Earth is 12,742 km. In other words, if you dug a hole down into the Earth, passed through the center of the Earth, and came out the other side, you would have dug a hole 12,742 km deep (on average). That's about 4 times longer than the diameter of the Moon. Read More ...

Project Icarus is a 21st century theoretical study of a mission to another star. Icarus aims to build on the work of the celebrated Daedalus project. Between the period 1973-1978 members of the BIS undertook a theoretical study of a flyby mission to Barnard's star 5.9 light years away. This was Project Daedalus and remains one of the most complete studies of an interstellar probe to date. The 54,000 ton two-stage vehicle was powered by inertial confinement fusion using electron beams to compress the D/He3 fusion capsules to ignition. It would obtain an eventual cruise velocity of 36,000km/s or 12% of light speed from over 700kN of thrust, burning at a specific impulse of 1 million seconds, reaching its destination in approximately 50 years.

Mysterious Radio Waves from Unknown Object in M82 Galaxy
There is something strange is lurking in the galactic neighborhood. An unknown object in galaxy M82 12 million light-years away has started sending out radio waves, and the emission does not look like anything seen anywhere in the universe before except perhaps by Ford Prefect. M82 is starburst galaxy five times as bright as the Milky Way and one hundred times as bright as our galaxy's center. "We don't know what it is," says co-discoverer Tom Muxlow of Jodrell Bank Centre for Astrophysics near Macclesfield, UK. But its apparent sideways velocity is four times the speed of light. This "superluminal" motion occurs usually in high-speed jets of material bursting out by black holes. Read More ...
Unsettled Mechanism of Supernova Detonation Gets a New Twist
Type Ia supernovae, often used to calibrate cosmological measurements, may arise from merging white dwarfs, after all
When stellar cataclysms known as type Ia supernovae flare up far across the universe, their brightness and consistency allow astronomers to use them as so-called standard candles to measure cosmological distances. Just over a decade ago, two teams used the supernovae to show that the universe is accelerating in its expansion due to the influence of dark energy, a shocking discovery that thrust type Ia supernovae into the astrophysical limelight. But how exactly did these cosmic mileposts come to be? Read More ...
It Takes a Giant Cosmos to Create Life and Mind + new Supernova Discovered to be the 'Creation-Machines' of the Cosmos
Excerpt from 'The Intelligent Universe', James Gardner ................... There is a time machine clearly visible right outside your front door. It’s easy to see—in fact, it’s impossible to overlook—although its awesome powers are generally ignored by all but a discerning few. The unearthly beauty, the ineffable grandeur, and the ingenuity of construction of this time machine are humbling to every human being who makes an effort to probe into the enigma of its origin and the mystery of its ultimate destiny. The time machine of which I speak is emphatically not of human origin. Indeed, a few venturesome scientists are beginning to entertain a truly incredible possibility: that this device is an artifact bequeathed to us by a supremely evolved intelligence that existed long, long ago and far, far away. All knowledgeable observers agree that the scope of its stupendous powers and the sheer delicacy of its miniscule moving parts seem nothing short of miraculous. Read More ...
Astronomers had found evidence of something that occurred before the (conventional) Big Bang
Our cosmos was "bruised" in collisions with other universes. Now astronomers have found the first evidence of these impacts in the cosmic microwave background. There's something exciting afoot in the world of cosmology. Last month, Roger Penrose at the University of Oxford and Vahe Gurzadyan at Yerevan State University in Armenia announced that they had found patterns of concentric circles in the cosmic microwave background, the echo of the Big Bang.

Fermilab scientists find evidence for significant matter-antimatter asymmetry
Batavia, Ill.—Scientists of the DZero collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced Friday, May 14, that they have found evidence for significant violation of matter-antimatter symmetry in the behavior of particles containing bottom quarks beyond what is expected in the current theory, the Standard Model of particle physics. The new result, submitted for publication in Physical Review D by the DZero collaboration, an international team of 500 physicists, indicates a one percent difference between the production of pairs of muons and pairs of antimuons in the decay of B mesons produced in high-energy collisions at Fermilab’s Tevatron particle collider.
The dominance of matter that we observe in the universe is possible only if there are differences in the behavior of particles and antiparticles. Although physicists have observed such differences (called “CP violation") in particle behavior for decades, these known differences are much too small to explain the observed dominance of matter over antimatter in the universe and are fully consistent with the Standard Model. If confirmed by further observations and analysis, the effect seen by DZero physicists could represent another step towards understanding the observed matter dominance by pointing to new physics phenomena beyond what we know today. Using unique features of their precision detector and newly developed analysis methods, the DZero scientists have shown that the probability that this measurement is consistent with any known effect is below 0.1 percent (3.2 standard deviations).
The DZero collaboration has found evidence for a new way in which elementary particles break the matter-antimatter symmetry of nature. This new type of CP violation is in disagreement with the predictions of the theoretical framework known as the Standard Model of particles and their interactions. The effect ultimately may help to explain why the universe is filled with matter while antimatter disappeared shortly after the big bang. Credit: DZero collaboration...
CP violation Are the laws of nature the same for matter and antimatter? Physicists use the term "CP" (for "charge parity") to talk about matter-antimatter symmetry. If nature treated matter and antimatter alike, then, in physics-speak, nature would be CP-symmetric. If not, CP is violated.
Experiments have shown that nature's weak force—which is responsible for the decay of particles—does in fact violate CP. Yet CP violation poses a mystery.
The big bang should have created equal amounts of matter and antimatter, with subsequent annihilation leaving neither behind. And yet, the observable universe has about ten billion galaxies that consist entirely of matter (protons, neutrons, and electrons) with no antimatter (antiprotons, antineutrons, and positrons). Very soon after the big bang, some forces must have caused the CP violation that skewed the equality in the number of matter and antimatter particles and left behind excess matter.
The weak force by itself can only explain a small amount of CP violation, not enough to leave matter for even a single galaxy. Some other hidden force—not accounted for in our Standard Model of particles and forces—must have been responsible for the extra CP violation that led to the universe we observe. Current and future particle accelerator experiments are designed to search for sources of CP violation large enough to account for the all-matter universe around us.
"This exciting new result provides evidence of deviations from the present theory in the decays of B mesons, in agreement with earlier hints," said Dmitri Denisov, co-spokesperson of the DZero experiment, one of two collider experiments at the Tevatron collider. Last year, physicists at both Tevatron experiments, DZero and CDF, observed such hints in studying particles made of a bottom quark and a strange quark.
When matter and anti-matter particles collide in high-energy collisions, they turn into energy and produce new particles and antiparticles. At the Fermilab proton-antiproton collider, scientists observe hundreds of millions every day. Similar processes occurring at the beginning of the universe should have left us with a universe with equal amounts of matter and anti-matter. But the world around is made of matter only and antiparticles can only be produced at colliders, in nuclear reactions or cosmic rays. “What happened to the antimatter?” is one of the central questions of 21st–century particle physics.
To obtain the new result, the DZero physicists performed the data analysis "blind," to avoid any bias based on what they observe. Only after a long period of verification of the analysis tools, did the DZero physicists look at the full data set. Experimenters reversed the polarity of their detector’s magnetic field during data collection to cancel instrumental effects.
The DZero result is based on the comparison of the distributions of positively and negatively charged muons (μ+ and μ-) emerging from high-energy proton-antiproton collisions produced by the Tevatron particle collider. A strong magnetic field inside the DZero particle detector forces the muons that emerge from those collisions to travel along a curved path. Two muons with opposite charge follow paths that curve in opposite direction (see graphic). Scientists first compared the muon distributions when the the magnetic field inside the DZero detector pointed in one direction (configuration 1) and then compared their distributions when the magnetic field had been reversed (configuration 2). If the matter-antimatter symmetry were perfect, the comparison of the muon distributions in the two configurations would yield the same result. Instead, the DZero experiment observed a one-percent deviation, evidence for a matter-antimatter asymmetry.
“Many of us felt goose bumps when we saw the result,” said Stefan Soldner-Rembold, co-spokesperson of DZero. “We knew we were seeing something beyond what we have seen before and beyond what current theories can explain.”
The precision of the DZero measurements is still limited by the number of collisions recorded so far by the experiment. Both CDF and DZero therefore continue to collect data and refine analyses to address this and many other fundamental questions.
“The Tevatron collider is operating extremely well, providing Fermilab scientists with unprecedented levels of data from high energy collisions to probe nature’s deepest secrets. This interesting result underlines the importance and scientific potential of the Tevatron program,” said Dennis Kovar, Associate Director for High Energy Physics in DOE’s Office of Science.
The DZero collaboration comprises about 500 scientists from 19 countries who designed and built the 5,500-ton DZero detector and now collect and reconstruct collision data. They research a wide range of Standard Model topics and search for new subatomic phenomena.
The DZero result is based on data collected over the last eight years by the DZero experiment: over 6 inverse femtobarns in total integrated luminosity, corresponding to hundreds of trillions of collisions between protons and antiprotons in the Tevatron collider.
“Tevatron collider experiments study high energy collisions in every detail, from searches for the Higgs boson, to precision measurement of particle properties, to searches for new and yet unknown laws of nature. I am delighted to see yet another exciting result from the Tevatron,” said Fermilab Director Pier Oddone.
DZero is an international experiment of about 500 physicists from 86 institutions in 19 countries. It is supported by the U.S. Department of Energy, the National Science Foundation and a number of international funding agencies.
Fermilab is a national laboratory funded by the Office of Science of the U.S. Department of Energy, operated under contract by Fermi Research Alliance, LLC.
The Fermilab accelerator complex accelerates protons and antiprotons close to the speed of light. The Tevatron collider, four miles in circumference, produces millions of proton-antiproton collisions per second, maximizing the chance for discovery. Two experiments, CDF and DZero, record the collisions to look for signs of new particles and subatomic processes.
The DZero detector records particles emerging from high-energy proton-antiproton collisions produced by the Tevatron. For this measurement of CP violation, scientists analyzed 10 trillion collisions collected over the last eight years.
