Abstract

We present the results of the search for the production of pairs of stops with final states consisting of a single isolated lepton, large missing transverse energy and at least four jets, performed by the CMS experiment. The data sample studied corresponds to an integrated luminosity of 19.5 fb-1 of proton-proton collisions at a center of mass energy of s=8 TeV. No excess above the standard model background expectation is observed. The results are used to exclude stop masses up to 650 GeV, for neutralino masses below 250 GeV, within the context of supersymmetric models that predict production of pairs of stops that decay either to a top quark and a neutralino or to a bottom quark and a chargino.
