SUMMARY:Prompt Signals and Displaced Vertices in the NMSSM - Giovanna Cott
 in (University of Cambridge\, Cavendish Laboratory)

DESCRIPTION:In this talk\, we study the LHC phenomenology of a model that 
 combines minimal Gauge Mediation and the Next-to-Minimal Supersymmetric St
 andard Model. The model possesses regions of parameter space where a longe
 r-lived lightest neutralino decays inside the detector resulting in potent
 ial displaced vertex (DV) signatures. We investigate current bounds on spa
 rticle masses and the discovery potential of the model\, both via conventi
 onal searches and via searches for displaced vertices. I will comment on t
 he reach of prompt searches and also summarize on current long-lived parti
 cle searches at the LHC\, including details of the ATLAS multi-track DV+je
 ts analysis we recast. We realize that the current DV searches cannot prob
 e this model due to b−quarks in the final state. We show how the displac
 ed vertex cuts might be relaxed in order to improve signal efficiency\, wh
 ile simultaneously applied prompt cuts reduce background\, resulting in a 
 much better sensitivity than either strategy alone and motivating a fully 
 fledged experimental study.
