Search for natural supersymmetry in events with top quark pairs and photons in pp collisions at $\sqrt{s} =$ 8 TeV

  title={Search for natural supersymmetry in events with top quark pairs and photons in pp collisions at \$\sqrt\{s\} =\$ 8 TeV},
  author={Cms Tracker Collaboration},
Results are presented from a search for natural gauge-mediated supersymmetry (SUSY) in a scenario in which the top squark is the lightest squark, the next-to-lightest SUSY particle is a bino-like neutralino, and the lightest SUSY particle is the gravitino. The strong production of top squark pairs can produce events with pairs of top quarks and neutralinos, with each bino-like neutralino decaying to a photon and a gravitino. The search is performed using a sample of pp collision data… Expand

Natural gauge mediation with a Bino next-to-lightest supersymmetric particle at the LHC.
The ATLAS diphoton search with 4.8 b(-1) of data is used to place limits in both the top-squark-gluino and neutralino-chargino mass planes, providing the first nontrivial constraints in natural gauge mediation models with a neutralino next-to-lightest supersymmetric particle decaying to photons.

Search for top squark and Higgsino production using diphoton Higgs boson decays.
Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking and lower limits at the 95% confidence level are set, excluding the top squark mass below 360 to 410 GeV, depending on the Higgsino mass. Expand
