【 摘 要 】

Charge parity reversal (CP) is an operation, by which a particle is converted into its corresponding antiparticle and all spatial directions inverted. CP is a symmetry which appears to be exact for the strong, electromagnetic and gravitational interactions, but not for the weak interaction. This asymmetry indicates fundamental differences in the behavior of matter and antimatter. According to the standard model (SM), CP violation can occur via the interactions that transform a quark into another quark with a different charge.
