CP violation

In particle physics, the violation of the combined conservation laws associated with charge conjugation, C (the operation of turning a particle into its antiparticle), and parity, P, by the weak force. In 1957 it was discovered that parity is violated in beta decay. No fully satisfactory explanation has been devised, but CP violation does enable physicists to make an absolute distinction between matter and antimatter.

Introduction CP-violation (CPV) (1) has been seen in the mixing of the neutral kaons, and recently also in the K[degrees] [right arrow] 2[pi] amplitudes [2] and in the decays of the neutral B-mesons [3].

The only such mechanism known to science is called CP-violation, first observed in 1964 in a group of particles called Kaons.

However, the CP-violation found in kaon decays, and incorporated into the Standard Model (SM) via the quark mixing mechanism, is too weak to explain the excess of baryons over antibaryons.
