In an S4 x Zn flavor-symmetric SO(10) SUSY model with type-II seesaw, the mu-to-e-gamma branching ratio constrains CMSSM, NUHM and NUSM parameter space, with MEG-II projected to probe most remaining regions.

abstract
We study lepton flavor-violating (LFV) processes within a supersymmetric type-I seesaw framework with flavor-blind universal boundary conditions, properly accounting for the effect of the neutrino sector on the dark matter relic abundance. We consider several possibilities for the neutrino Yukawa coupling matrix and show that in regions of SUSY parameter space that yield the correct neutralino relic density, LFV rates can differ from naive estimates by up to two orders of magnitude. Contrary to common belief, we find that current LFV limits do not exclude neutrino Yukawa couplings larger than top Yukawa couplings. We introduce the ISAJET-M program that was used for the computations.

Analytical Soft SUSY Spectrum in Supersymmetric Models in Light of $ S_{4} \times Z_{n} $ flavor symmetric SUSY SO(10) theory
In an S4 x Zn flavor-symmetric SO(10) SUSY model with type-II seesaw, the mu-to-e-gamma branching ratio constrains CMSSM, NUHM and NUSM parameter space, with MEG-II projected to probe most remaining regions.
