CERN Discovery Of Unevenly-Decaying Particle Gives Clue Into Why There's Not More Antimatter Around

A team working with data from CERN's Large Hadron Collider says it has discovered a particle that decays unevenly into matter and antimatter.

The lab near Geneva said Wednesday that the particle called 'B0s' is the fourth sub-atomic particle known to prefer matter over antimatter.

Theory posits that the Big Bang produced equal amounts of each, and scientists have puzzled over why matter now dominates.

The discovery of the first matter-antimatter asymmetry earned two scientists at Brookhaven Laboratory in New York a Nobel Prize in 1980.

Team spokesman Pierluigi Campana said the find was predicted by the standard model of physics but "some interesting discrepancies demand more detailed studies."
