Descripción
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 accumulated by the CMS experiment at √{s}=8 TeV,
corresponding to an integrated luminosity of 19.7 fb-1. The
final state consists of a lepton (electron or muon), jets, and one or
two photons. The imbalance in transverse momentum in the events is
compared with the expected spectrum from standard model processes. No
excess event yield is observed beyond the expected background, and the
result is interpreted in the context of a general model of
gauge-mediated SUSY breaking that leads to exclusion of top squark
masses below 650-730 GeV. [Figure not available: see fulltext.]
