Supercomputing the difference between matter and antimatter

(PhysOrg.com) — 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 experimental evidence of charge-parity (CP) violation — a lack of symmetry between particles and their corresponding antiparticles that may hold the answer to the question “Why are we made of matter and not antimatter?”
