Lepton-Flavor Violation in the Supersymmetric Standard Model with Seesaw-Induced Neutrino Masses

Abstract

We examine the lepton-flavor violation caused by a Yukawa coupling matrix $y_{\hat{I}½,ij}$ for right-handed neutrinos in the supersymmetric standard model. We stress that decay rates for $\ddot{I}„\to \hat{I}¼{\hat{I}}^3$ and $\hat{I}¼\to e{\hat{I}}^3$ may reach the range to be accessible to near future experiments if left-right mixing terms in the slepton mass matrix are substantially large.
