CERN Finds Matter-Antimatter Asymmetry
2013-04-24 14:40:18

Lee Rannals for redOrbit.com - Your Universe Online Scientists at CERN have submitted a paper to be published in the journal Physical Review Letters about the first observation of matter-antimatter asymmetry. The team said they made the observation while looking at the decay rate of particles known as B0s mesons. They now say that their findings indicate that antimatter decays at a faster rate than antimatter. Matter and antimatter are thought to have existed in equal amounts at the...

SLAC National Accelerator Laboratory Time's quantum arrow has a preferred direction, new analysis shows Time marches relentlessly forward for you and me; watch a movie in reverse, and you´ll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse — a concept known as time reversal...

Research spurs innovations in computing technology that drive advances to supercomputers An international collaboration of scientists has reported a landmark calculation of the decay process of a kaon into two pions, using breakthrough techniques on some of the world's fastest supercomputers. This is the same subatomic particle decay explored in a 1964 Nobel Prize-winning experiment performed at the U.S. Department of Energy's Brookhaven National Laboratory (BNL), which revealed the first...

A University of Warwick physicist has produced a galaxy sized solution which explains one of the outstanding puzzles of particle physics, while leaving the door open to the related conundrum of why different amounts of matter and antimatter seem to have survived the birth of our Universe. Physicists would like a neat universe where the laws of physics are so universal that every particle and its antiparticle behave in the same way. However in recent years experimental observations of...

Physicists study rare particles to learn why the universe has more matter than antimatter Using data from experiments performed in 2010 at the Large Hadron Collider (LHC), the world's largest particle accelerator near Geneva, Switzerland, scientists are studying rare particle decays that could explain why the universe has more matter than antimatter. Led by Sheldon Stone, a physicist at Syracuse University, a group of scientists recently published their first observations of two different...

UC Riverside physicists involved in the international research; new result brings us closer to understanding the universe and its origins Why is there matter in the universe and not antimatter, its opposite? Physicists at Fermi National Accelerator Laboratory, including John Ellison, a professor of physics at UC Riverside, have announced that they have found evidence for a significant violation of matter-antimatter symmetry in decays of B-mesons, which are exotic particles produced in high...

By Dennis Overbye A U.S. and two Japanese physicists won the Nobel Prize in Physics on Tuesday for their work exploring the hidden symmetries between elementary particles that are the deepest constituents of nature. Yoichiro Nambu, of the University of Chicago's Enrico Fermi Institute, will receive half of the 10 million kroner prize, or about $1.4 million, awarded by the Royal Swedish Academy of Sciences. Makoto Kobayashi, of the High Energy Accelerator Research Organization in...

Two Japanese scientists and a Japanese-born American have been awarded the 2008 Nobel Prize in physics for their work with subatomic particles which provided new insights into the nature of matter. The Royal Swedish Academy of Sciences announced the winners - Yoichiro Nambu, Makoto Kobayashi and Toshihide Maskawa "“ on Tuesday. American Yoichiro Nambu, 87, of the University of Chicago, won half of the prize for the discovery of a mechanism called spontaneous broken symmetry in...
