About absence of oscillations at CP violation and presence of interference between KS-, KL-meson states in the system of K0 mesons

Two approaches to the description of K0-, K0-bar-meson transitions into K10 mesons at CP violation in weak interactions are considered. The first approach uses the standard theory of oscillations and the second approach supposes that (KS, KL) states which arise at CP violation are normalized but not orthogonal state functions, then there arise interferences between these states but not oscillations. It is necessary to remark that the available experimental data are in good agreement with the second approach. So, we come to the conclusion that oscillations do not arise at CP violation in weak interactions in the system of K0 mesons. Only interference between KS and KL states takes place here.
