Descripción
Results are reported from a search for supersymmetry with gauge-mediated
supersymmetry breaking in electroweak production. Final states with
photons and large missing transverse energy
(ETmiss) were examined. The data sample was
collected in pp collisions at √{ s} = 8TeV with the CMS detector at
the LHC and corresponds to 7.4fb-1. The analysis focuses on
scenarios in which the lightest neutralino has bino- or wino-like
components, resulting in decays to photons and gravitinos, where the
gravitinos escape undetected. The data were obtained using a specially
designed trigger with dedicated low thresholds, providing good
sensitivity to signatures with photons, ETmiss ,
and low hadronic energy. No excess of events over the standard model
expectation is observed. The results are interpreted using the model of
general gauge mediation. With the wino mass fixed at 10GeV above that of
the bino, wino masses below 710GeV are excluded at 95% confidence level.
Constraints are also set in the context of two simplified models, for
which the analysis sets the lowest cross section limits on the
electroweak production of supersymmetric particles.
