• 論文の詳細を見る

• A phenomenological and comprehensive study is given of the (possible) violation of CP, T and CPT symmetries in the K^0-K^^-^0 system. Relevant decay amplitudes as well as mixing parameters are parametrized in a rephasing-invariant way, and formulae relevant to phenomenological analyses are derived. An attempt is made to derive constraints on these CP, T and/or CPT violating parameters from available experimental data. It is found, among other things, that the parameters which signal both CP and CPT violations are subject to large errors and at best only one or two orders smaller than those which signal both CP and T violations, the latter being known to be of order 10^<-3>. Furthermore, it is pointed out that those parameters which signal both T and CPT violations but not CP violation are not yet well constrained experimentally.
