Abstract

For this year’s 8 TeV run of the LHC we lay out different strategies to search for scalar top pairs. We show results for the hadronic and for the semi-leptonic channels based on hadronic top tagging. For the di-lepton channel we illustrate the impact of transverse mass variables. Each of our signal-to-background ratios ranges around unity for a stop mass around 400 GeV. The combined signal significances show that dedicated stop searches are becoming sensitive over a non-negligible part of parameter space.
