摘要：
This work considers the K-0, (K) over bar (0) meson mixings and the oscillations via K-1(0), K-2(0) meson states at strangeness violation by the weak interactions and the K-1(0), K-2(0) meson mixings and oscillations via K-S, K-L meson states at CP violation by the weak interactions with taking into account decay widths. We worked in the framework of the masses mixing scheme. It is shown that K-1(0) (K-S) meson states appear at big distances from the K-0 mesons source after their decays (tau(2) >> tau(1)) due to oscillations of residual K-2(0) (K-L) mesons and then again one can see short living K-1(0) (K-S) mesons. It is implied that K-L <-> K-S meson oscillations are absent. The case when at CP violation the unitarity is violated is considered. The general expressions for the probabilities of meson oscillations (transitions) are given.
