A Search for a Simplified Model of Supersymmetry with Light Sbottoms and Higgsinos Using Higgs to Diphoton Decays
We present a search for a simplified supersymmetric model with pair-produced light supersymmetric bottom quarks decaying to neutralinos. Higgs-type neutralinos (Higgsinos) decay to the Higgs boson and LSP, with at least one Higgs bo son decaying to a diphoton system. Events with at least two b-jets and a photon pair in the Higgs-tagged invariant mass window are considered. In 36.2 fb-1 of proton-proton collision data collected at the CMS experiment at √s = 13 TeV, we find no evidence of signal and set lower limits on the production of the bottom squark at a 95% confidence level at masses of below 350 GeV, with a Higgsino mass of 150 GeV or less.
