Abstract

We study a grand unified theories inspired supersymmetric model with nonuniversal gaugino masses that can explain the observed muon g2 anomaly while simultaneously accommodating an enhancement or suppression in the hγγ decay channel. In order to accommodate these observations and mh125 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 Rγγ1.1 is 100GeVmτ˜200GeV. The constraint on the slepton masses, particularly on the smuons, arising from considerations of muon g2 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 mg˜4.5TeV and mt˜13.5TeV, which makes it challenging for these to be observed at the 14 TeV LHC.
