Phase effects from the general neutrino Yukawa matrix on lepton flavor violation

Abstract

We examine contributions from Majorana phases to lepton flavor violating processes in the framework of the minimal supersymmetric standard model with heavy right-handed neutrinos. All phases in the complex neutrino Yukawa matrix are taken into account in our study. We find that in the scenario with universal soft-breaking terms sizable phase effects can appear on the lepton flavor violating processes such as $\mu \to e\gamma$, $\tau \to e\gamma$, and $\tau \to \mu \gamma$. In particular, the branching ratio of $\mu \to e\gamma$ can be considerably enhanced due to the Majorana phases, so that it can be much greater than that of $\tau \to \mu \gamma$.
