How Georgi-Jarlskog and SUSY-SO(10) imply a measurable rate for mu->e gamma

Abstract

Slepton mass matrices have been analyzed in an SO(10) SUSY-GUT, with soft-breaking terms generated at Planck scale. Higher dimensional operators consistent with 4-d string constructions are used in order to generate a Georgi-Jarlskog (G-J) Yukawa texture at \mgut. Radiative corrections between \mpl\ and \mgut\ generate a substantial non-universality in the $\tilde{\mu }-\tilde{e}$ sector. This non-universality originates in the flavor dependence of the Higgs assignments required for the G-J texture, and is unrelated to the large top Yukawa. The resulting branching ratio for mu->e could make this process observable for large sectors of the MSSM parameter space, with a factor of 10 improvement in statistics.
