Impact of LHC Searches on NLSP Top Squark and Gluino Mass

Understand

We explore the implications of 7 TeV LHC searches for a scenario in which one of the stops is the next-to lightest supersymmetric particle (NLSP).

• The NLSP stop (\tilde{t}_1) is assumed to decay exclusively into neutralino and charm quark.
• We consider processes where the stops are pair produced together with a hard QCD jet.
• We also consider stop quarks from gluino decays, \tilde{g}\to t\tilde{t}_1^\ast+\bar{t}\tilde{t}_1.
