A Predictive Yukawa Unified SO(10) Model: Higgs and Sparticle Masses

Understand

We revisit a class of supersymmetric SO(10) models with t-b-tau Yukawa coupling unification condition, with emphasis on the prediction of the Higgs mass.

• We discuss qualitative features in this model that lead to a Higgs mass prediction close to 125 GeV.
• We show this with two distinct computing packages, Isajet and SuSpect, and also show that they yield similar global features in the parameter space of this model.
• We find that t-b-tau Yukawa coupling unification prefers values of the CP-odd Higgs mass m_{A} to be around 600 GeV, with all colored sparticle masses above 3 TeV.
