Oscillations between members of flavoured, electrically neutral meson pairs and the CP violation are phenomena strictly connected with the mixing. However, CP is more general, having been observed also in the decay of charged mesons.
CP violation was first observed in the neutral K system. We see the states of definite strangeness, those of definite CP and those with definite mass and lifetime. The oscillation between the former states, the mathematical expressions and the experimental evidence.
The oscillations and CP violation in the B0 system, and the beautiful experimental results obtained at dedicated high-luminosity electron–positron colliders, the ‘beauty factories’. Beauty physics at the dedicated experiment LHCb at LHC, in particular for the B0, that is not accessible to beauty factories. Examples of CP violation in B0. The recent discovery of CP violation in the charm sector.
How the many different measurements can be put together to test the SM with the unitary triangle.
