Abstract
We revisit the minimal supersymmetric SU(5) grand unified theory with three right-handed neutrinos in which universality conditions for soft-supersymmetry breaking parameters are imposed at an input scale above the unification scale. If the Majorana masses for the neutrinos are around 1015 GeV, large mixing angles and phases in the neutrino sector lead to flavor violation and CP violation in the right-handed down-squark and left-handed slepton sectors. Since the observed Higgs boson mass and the proton decay constraints indicate that sfermions have masses larger than a few TeV, flavor and CP constraints are less restrictive. We explore the constraints on models with universal soft-supersymmetry breaking input parameters coming from proton stability, electric dipole moments, ���e�� decays, and the Higgs mass observed at the LHC. Regions compatible with all constraints can be found if nonzero A-terms are taken. (c) 2018 authors. Published by the American Physical Society
