An international collaboration of physicists conducting experiments at the Department of Energy's Stanford Linear Accelerator Center (SLAC) has discovered a second fundamental difference between the behavior of matter and that of antimatter. They observed this intriguing phenomenon -- known as charge-parity (CP) violation and first seen decades ago in experiments with another particle -- in disintegrations of heavy, short-lived subatomic particles called B mesons. The collaboration reported its result in a paper submitted July 5 for publication in Physical Review Letters, a leading scientific journal.
