Antimatter would have wiped out almost everything after the Big Bang. Why was it so close? The Cern comes closer to the answer.

CERN experts observed for the first time disintegrations of barions, particles that make up most of the matter of the observable universe, a phenomenon that was predicted in the 1960s, but had never been proven in particles before.

By analyzing years of collision data of the Great Hadron Collider (LHC), physicists have for the first time observed the breaking—or violation—of the load-parity symmetry in the disintegration of baryon particles, revealing a difference in behavior between matter and antimatter. Since baryons make up the bulk of matter in the Universe, this discovery constitutes an essential piece of the puzzle aimed at explaining why matter prevailed over antim…

One of the deeper enigmas of modern physics is why the Universe is composed almost exclusively of matter and was not completely annihilated by antimatter after the Big Bang. A new observation made in the CERN’s Great Hadron Collider (LHC) could represent a key piece to solve this puzzle. A team of researchers has found evidence of a violation of load-parity symmetry (CP) in barions, a type of subatomic particles that make up most of the visible …
