Why matter matters in the universeA new physics discovery explores why there is more matter than antimatter in the universe. The latest research findings, which involved significant contributions from physicists at the University of Melbourne, have been recently ... |
Physicists: After 30 years of study, rare particle confirms predictionHigh-energy physicists devoted to recreating the conditions at the beginning of the universe have for the first time observed a new way to produce those basic particles of atoms, protons and neutrons. |
A 'Golden Channel' for New PhysicsA group of physicists has dubbed a particular particle decay, the decay of the Bs meson into a neutral kaon and neutral antikaon, as a “golden channel” for new physics, suggesting that probing and studying the decay could ... |
Latest Supercomputer Calculations Support the Six-Quark TheoryA new calculation, reported in the January 25, 2008 issue of Physical Review Letters, confirms the six-quark theory of particle-anti-particle asymmetry. This is the first complete calculation of this phenomenon to ... |
 New form of matter-antimatter transformation observed for first timeFor the first time, scientists of the BaBar experiment at the Department of Energy's Stanford Linear Accelerator Center (SLAC) have observed the transition of one type of particle, the neutral D-meson, into ... |
Particle X in rare decay could belong to a new physics modelA particle that may mediate the rare decay of a Sigma-plus hyperon appears to have close affiliations with a light Higgs boson found in one supersymmetric model—an interpretation suggesting unambiguous evidence for physics ... |
 Particle decay may point to New PhysicsA tiny flaw has caught the attention of physicists: the Standard Model (SM) predicts that the B meson mixing phase should be measured at nearly the same result using two different classes of decay modes. However, ... |
New Form of CP Violation DiscoveredFinding something expected has brought researchers at the Department of Energy's Stanford Linear Accelerator Center (SLAC) one step closer to discovering the unexpected. |
 Physicists observe subatomic quick-change artistIt's taken 19 long years of painstaking, high-precision experiments, but it's finally official: Physicists have announced the observation of a subatomic particle known as the Bs (pronounced "B sub ... |
 Search for Rare Particle Decay Comes Up ShortBased on work performed at a large particle detector known as the BaBaR experiment, scientists announced recently that they do not see evidence to support theoretical predictions that an extremely rare particle ... |
 Inside BaBar's Control RoomDay and night, weekends, weekdays, and holidays, physicists from around the world take shifts in BaBar's Interaction Region 2 control room. The BaBar detector records the products of the positron-electron collisions ... |
 Physicists size up the 'unitarity triangle'B factory experiments at the Stanford Linear Accelerator Center (SLAC) in the USA and at the High Energy Accelerator Research Organization (KEK) in Japan have reached a new milestone in the quest to understand ... |
 Scientists present a precision measurement of a subtle dance between matter and antimatterScientists of the CDF collaboration at the DOE's Fermi National Accelerator Laboratory announced today the precision measurement of extremely rapid transitions between matter and antimatter. |
 What happened to the antimatter?Scientists of the DZero collider detector collaboration at the Department of Energy's Fermi National Accelerator Laboratory have announced that their data on the properties of a subatomic particle, the B_s ... |
 Spin Structure of Protons and Neutrons Normally, we think of building blocks as static objects. For instance, the brick and mortar used to build the local bank remain pretty much the same from the day it's built to the day it's torn down. But the ... |
