Supersymmetric CP violation ${ϵ}^{\prime }/ϵ$ due to asymmetric A-matrix

Abstract

We study contributions of supersymmetric CP phases to the CP violation ${ϵ}^{\prime }/ϵ$ in models with asymmetric $A$-matrices. We consider asymmetric $A$-matrices, which are obtained from string-inspired supergravity. We show that a certain type of asymmetry of $A$-matrices enhances supersymmetric contributions to the CP violation ${ϵ}^{\prime }/ϵ$ and the supersymmetric contribution to ${ϵ}^{\prime }/ϵ$ can be of order of the KTeV result, ${ϵ}^{\prime }/ϵ\sim 10^{-3}$.
