Flavor-Tuned 125 GeV SUSY Higgs Boson at the LHC: MSSM and NATURAL SUSY TESTS

Abstract

We show that an enhanced two-photon signal of the Higgs boson, h, observed with 125 GeV mass by the ATLAS and CMS collaborations, can be obtained if it is identified principally with the neutral $H_u^0$ of the two Higgs doublets of minimal Supersymmetry. We focus on sparticles and the pseudoscalar Higgs $A$ at the TeV scale. The off-diagonal element of the (Hu0,Hd0) mass matrix in the flavor basis must be suppressed, and this requires both a large Higgsino mass parameter, mu \sim TeV, and large tan beta. A MSSM sum rule is derived that relates gamma gamma and bb rates, and the gamma gamma enhancement predicts the bb reduction. On the contrary, Natural SUSY requires | mu | < 0.5 TeV, for which gamma gamma is reduced and $b\bar{b}$ is enhanced. This conclusion is independent of the mA-value and the SUSY quantum correction Deltab. Relative tau tau to bb rates are sensitive to Deltab.
