CP-violation and unitarity triangle test of the Standard Model

Abstract

Phenomenological issues of the 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 the CP violation in $K_L^0$ and $B_d^0({\bar{B}}_d^0)$-decays. The standard unitarity triangle fit of the existing data is discussed. In appendix A we compare the $K^0\leftrightarrows {\bar{K}}^0$, $B_{d,s}^0\leftrightarrows {\bar{B}}_{d,s}^0$ etc oscillations with neutrino oscillations. In Appendix B we derive the evolution equation for $M^0-{\bar{M}}^0$ system in the Weisskopf-Wigner approximation.
