Cpviolation cpv was discovered in 1964 in the weak decays of neutral kaons. It was long thought that cp was an exact symmetry in nature. Cp and other symmetries of symmetries andreas trautner. Cp violation will be discussed in detail in the next lecture 14. The investigation of discrete symmetries is a fascinating subject which has been central to the agenda of physics research for fifty years, and has been the target of many experiments, ongoing and. Symmetries of symmetries and geometrical cp violation. Therefore, not allowing for an enhancement of the discrete symmetry. The book discusses discrete symmetries parity, charge conjugation, time reversal, and of course cp symmetry in microscopic atomic, nuclear, and particle.
