SO(10) Yukawa unification after the first run of the LHC

Abstract

In this talk we discuss SO(10) Yukawa unification and its ramifications for phenomenology. The initial constraints come from fitting the top, bottom and tau masses, requiring large tan β ∼ 50 and particular values for soft SUSY breaking parameters. We perform a global χ2 analysis, fitting the recently observed ‘Higgs’ with mass of order 125 GeV in addition to fermion masses and mixing angles and several flavor violating observables. We discuss two distinct GUT scale boundary conditions for soft SUSY breaking masses. In both cases we have a universal cubic scalar parameter, A0. In the first case we consider universal gaugino masses, and universal scalar masses, m16, for squarks and sleptons; while in the latter case we have non-universal gaugino masses and either universal scalar masses, m16, for squarks and sleptons or D-term splitting of scalar masses. We discuss the spectrum of SUSY particle masses and consequences for the LHC.
