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 [?] of the two Higgs doublets of minimal supersymmetry. We focus on sparticles and the pseudoscalar Higgs A with TeV masses. The off-diagonal element of the [?] mass matrix in the flavor basis must be suppressed, and this requires a large Higgsino mass parameter, [?] ~ TeV, and large tan[?]. A minimal supersymmetric Standard Model sum rule is derived that relates [?][?] reduction. On the contrary, natural supersymmetry requires [?] < ~0.5 TeV, for which [?][?] is reduced and [?][?] is enhanced. This conclusion is independent of the m_A value and the supersymmetry quantum correction [?]. Relative [?] to [?] rates are sensitive of [?].
