Chargino contributions to ${ϵ}^{\prime }/ϵ$ in the left-right supersymmetric model

Abstract

We analyze the chargino contributions to the CP violating ratio ${ϵ}^{\prime }/ϵ$ in the left-right supersymmetric model. We study the possibility that these contributions alone can saturate the experimental value of ${ϵ}^{\prime }/ϵ$. We derive conservative bounds on supersymmetric flavor violation parameters in the up squark LL, RR, LR and RL sectors, using the mass insertion approximation. While the LL bounds are found to be consistent with the MSSM values, the LR constraints are new and much stronger.
