K⁰ and CP

Abstract

The phenomenological theory of the neutral K−mesons (kaons) is summarized. The consequences of the C, CP, CPT symmetries are discussed in details. Finally, the different suggestions are reviewed, concerning the explanation of the CP violating K0L → π+ π− decay.

Weak decays of the metastable hadrons

“…By applying perturbation theory we obtain a first order differential equation for the coefficients c , ( t ) ; we look for the solutions with the ansatz and get the following homogeneous equations for aK and uK [94] : I n order to make the square root unique we may require Im A > 0. As we see from Eq.…”
