Search for supersymmetry in events with one lepton in proton-proton collisions at sqrt(s)=13 TeV with the CMS experiment

A search for supersymmetry in events with a single electron or muon is performed on proton-proton collision data with the CMS experiment at a center-of-mass energy of 13 TeV, in a dataset corresponding to an integrated luminosity of 2.3 fb$^{-1}$. Several exclusive search regions are defined, based on the number of b-tagged jets, the scalar sum of all jet transverse momenta, and the scalar sum of the transverse missing momentum and transverse lepton momentum. The observed yields are compatible with predictions from standard model processes. The results are interpreted in two simplified models describing gluino pair production. In a model where each gluino decays to top quarks and a neutralino, gluinos with masses up to 1.575 TeV are excluded for neutralino masses below 600 GeV. In the second model, each gluino decays to two light quarks and an intermediate chargino, with the latter decaying to a W boson and a neutralino. Here, gluino masses below 1.4 TeV are excluded for neutralino masses below 725 GeV, assuming a chargino with mass midway between the gluino and neutralino mass.
