Description
A search for supersymmetry in events with a single electron or muon, hadronic jets and missing transverse momentum is presented. The data corespond to 35.9 fb−1 of proton-proton collisions recorded in 2016 by the CMS experiment at a center-of-mass energy of 13 TeV. The events are sorted into several exclusive search samples based on the number of jets and b-tagged jets, the scalar sum of the jet transverse momenta, and the scalar sum of the missing transverse momentum and the transverse momentum of the lepton. The numbers of events observed in all search samples are consistent with the expectations from standard model processes, and the results are used to set lower limits on superymmetric particle masses in the context of two simplified models of gluino pair production. In the first model, each gluino decays via a three- body process to a top quark-antiquark pair and a neutralino, which is assumed to escape udetected. Gluinos with masses up to 1.8 TeV are excluded for neutralino masses below 800 GeV. In the second model, each gluino decays via a three-body process to a light quark-antiquark pair and a chargino, which subsequently decays to a W boson and a neutralino. The mass of the chargino is taken to be midway between the gluino and neutralino masses. In this model, gluinos with masses below 1.9 TeV are excluded for neutralino masses below 300 GeV.
