Violation of CP invariance for neutral K0-, D0-, Bd0-, Bs0-mesons and quarks in weak interactions

CP violation in the Kobayashi-Maskawa matrix was introduced by using phase which is the same for the three families of quarks. However, analysis of CP violation of mesons has shown that new small-angle mixings appear besides of CP phases. This work is devoted to the consideration of possible schemes for introducing CP violation. It is noted that in general case it is not correct to use CP phase only for the first and third quark families as it is usually introduced. CP phase has to be presented for all quark families, and moreover these phases cannot be the same for all families. Besides, a common case of CP violation was considered for K0, D0, Bd0, Bs0 mesons, where mixing angles and phases are present at CP violation. Expressions for transition probabilities for these processes are given. In conclusion, mixing of d, s, b quarks at CP violation was considered with taking into account their angle mixings and phases.
