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

In supersymmetric SO(10) grand unified models, we examine the lepton flavor violation process μ→eγ from having the SU(2)RxU(1)B-L gauge symmetry broken at an intermediate scale MI below the SO(10) grand unification scale MG. Even in the case that supersymmetry is broken by universal soft terms introduced at the scale MG, we find significant rates for μ→eγ with MI∼1012 GeV or less. These rates are further enhanced if the universal soft terms appear at a scale greater than MG. copyright 1996 The American Physical Society
