Revisiting flavor and C P violation in supersymmetric S U (5 ) with right-handed neutrinos
Abstract
We revisit the minimal supersymmetric S U (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 1 015 GeV , large mixing angles and phases in the neutrino sector lead to flavor violation and C P 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 C P constraints are less restrictive. We explore the constraints on models with universal soft-supersymmetry breaking input parameters coming from proton stability, electric dipole moments, μ →e γ decays, and the Higgs mass observed at the LHC. Regions compatible with all constraints can be found if nonzero A -terms are taken.
