Enhancement of $ε'/ε$ in the SU(2)$_L \timesSU(2)_R \times$U(1) model

We explore the possible enhancement of direct CP violating parameter $\epe$ in the general left-right model based on the SU(2)$_L \timesSU(2)_R \times$U(1) gauge group. The mixing matrix of right-handed quarks, $V_{CKM}^R$ is observable in the left-right model, and provides new source of CP violating phase. We calculate the parameter $\epe$ in the left-right model and show that the new phases from $V_{CKM}^R$ can yield the sizable contribution to the direct CP violation enough to satisfy the recent measurements of Re$(\epe)$ from Fermilab KTeV and CERN NA48 experiments.
