the symmetries C （particle-antiparticle interchange） and P （space inversion） hold for strong and electromagnetic interactions. After the discovery of large C and P violation in the weak interactions, it appeared that the product CP was a good symmetry. In 1964 CP violation was observed in K^0 decays at a level given by the parameter e ≈ 2.3 ×10^-3.
