$\mu \to e\gamma$ in supersymmetric multi U(1) models with an abelian gaugino mixing

Abstract

A lepton flavor violating process $\mu \to e\gamma$ is investigated in the supersymmetric extra U(1) models, which often appear as the low energy effective models of superstring and can potentially solve the $\mu$-problem. The branching ratio of this process is calculated. It is numerically estimated and compared with that of the MSSM. In this study we take account of an abelian gaugino kinetic term mixing and discuss its influence on this process. The possibility to find the extra gauge structure through this process is discussed.
