New limits on the SUSY Higgs boson mass

We present new upper limits on the light Higgs boson mass m h in supersymmetric models. We consider two gravity-mediated models (with and without universal scalar masses) and two gauge-mediated models (with a 5 + 5 or 10 + 10 messenger sector). We impose standard phenomenological constraints, as wel...

Description
Summary:We present new upper limits on the light Higgs boson mass m h in supersymmetric models. We consider two gravity-mediated models (with and without universal scalar masses) and two gauge-mediated models (with a 5 + 5 or 10 + 10 messenger sector). We impose standard phenomenological constraints, as well as SU(5) Yukawa coupling unification. Requiring that the bottom and tau Yukawa couplings meet at the unification scale to within 15%, we find the upper limit m h
