Abstract

Phenomenological issues of CP violation in the quark sector of the Standard Model are discussed. We consider quark mixing in the SM, standard, and Wolfenstein parametrization of the CKM mixing matrix and unitarity triangle. We discuss the phenomenology of CP violation in K 0 and B 0 ( B_d⁰ )-decays. The standard unitarity triangle fit of the existing data is discussed. In appendix A we compare the K 0 ⇆ K⁰ , B 0 ⇆ B_{d, s}⁰ , etc. oscillations with neutrino oscillations. In Appendix B we derive the evolution equation for the M − M⁰ system in the Weisskopf-Wigner approximation.
