Intermediate scale as a source of lepton flavor violation in SUSY SO(10)

Abstract

In supersymmetric SO(10) grand unified models, we examine the lepton flavor violation process $μ\rightarrow eγ$ from having the SU(2)$_R\times $U(1)$_{B-L}$ gauge symmetry broken at an intermediate scale $M_I$ below the SO(10) grand unification scale $M_G$. Even in the case that supersymmetry is broken by universal soft terms introduced at the scale $M_G$, we find significant rates for $μ\rightarrow eγ$ with $M_I \sim 10^{12}$ GeV or less. These rates are further enhanced if the universal soft terms appear at a scale greater than $M_G$.
