Higgs boson mass from orbifold GUTs with split supersymmetry

摘要

We consider orbifold GUTs with N = 1 supersymmetry in which the Standard Model (SM) gauge couplings are unified at M-GUT similar or equal to 2 x 10(16) GeV with one of the third family (charged) Yukawa couplings. With split supersymmetry the SM Higgs mass is estimated to be 131 +/- 10 GeV for gauge-top quark Yukawa unification, which increases to 146 +/- 8 GeV for gauge-bottom quark (or gauge-tau lepton) Yukawa unification.
