Abstract
In this proceedings, the latest results from the CMS collaboration on searches for Supersymmetry with Gauge Mediated Supersymmetry Breaking (GMSB) in final states with photons and leptons are presented using pp collision data from the 7 and 8 TeV LHC run. The experimental results are interpreted in terms of weak as well as strong production of SUSY particles, followed by cascade decays to a Gravitino as lightest supersymmetric particle.
Highlights
The CMS experiment [1] at the Large Hadron Collider (LHC) has accumulated data corresponding to an integrated luminosity of around 5 fb−1 in 2011 and around 20 fb−1
The CMS experiment has pursued the searches for the super-partner particles
The gauge mediated supersymmetry breaking (GMSB) model has been motivated at low energy scale where the required breaking of supersymmetry can occur in hidden sector by a mean of couping to the visible sector through the Standard Model (SM) gauge interactions [2]
Summary
The CMS experiment [1] at the Large Hadron Collider (LHC) has accumulated data corresponding to an integrated luminosity of around 5 fb−1 in 2011 and around 20 fb−1. Since the splitting the charged and neutral wino becomes small, the charged wino becomes co-NLSP which decays directly to a gravitino LSP and a W boson In this proceedings, the results of GMSB searches by the time LHCP2013 conference with the fraction of collected data which is correspond to an integrated luminosity of up to 9.2 fb−1 at 8 TeV as well as 5 fb−1 at 7 TeV will be presented. Two final state topologies has been considered in the searches with photons using data corresponding to an integrated luminosity of 4 fb−1 at 8 TeV [5]. For wino-like neutralino scenario, mass below 850 GeV has been excluded in single-photon selection This is a significant improvement with respect to 7 TeV result [4].
