Model ofCViolation in Semistrong Interactions

Abstract

A simple model of $C$ violation in semistrong interactions is proposed. The basic semistrong interaction is an "equal" mixture of $C$-invariant and -noninvariant parts. The former part is the coupling between two neutral vector mesons (Sakurai's interaction), and the latter is the coupling between neutral vector and scalar mesons. The nature of this particular interaction and the possible experimental consequences are discussed. The small ${{K}_{2}}^{0}\ensuremath{\rightarrow}2\ensuremath{\pi}$ decay rate can be consistent with our model. Also the $\ensuremath{\rho}\ensuremath{\eta}\ensuremath{\pi}$ coupling and the $C$-violating effect in the ${\ensuremath{\Sigma}}^{0}\ensuremath{\rightarrow}\ensuremath{\Lambda}{e}^{+}{e}^{\ensuremath{-}}$ decay are calculated.
