Title: GUT-inspired supersymmetric model for h γ γ and the muon g - 2

We study a grand unified theories inspired supersymmetric model with nonuniversal gaugino masses that can explain the observed muon g-2 anomaly while simultaneously accommodating an enhancement or suppression in the h→γγ decay channel. In order to accommodate these observations and m h≅125 to 126 GeV, the model requires a spectrum consisting of relatively light sleptons whereas the colored sparticles are heavy. The predicted stau mass range corresponding to R γγ≥1.1 is 100 GeV≲m τ˜≲200 GeV. The constraint on the slepton masses, particularly on the smuons, arising from considerations of muon g-2 is somewhat milder. The slepton masses in this case are predicted to lie in the few hundred GeV range. The colored sparticles turn out to be considerably heavier with m ≳4.5 TeV and m t˜₁≳3.5 TeV, which makes it challenging for these to be observed at the 14 TeV LHC.
