Search for supersymmetry in events with one lepton and multiple jets in proton-proton collisions at sqrt(s)=13 TeV in 2016

A search for supersymmetry is performed in events with a single electron or muon in proton-proton collisions at a center-of-mass energy of 13 TeV in 2016. The data were recorded by the CMS experiment at the LHC, and correspond to an integrated luminosity of 12.9 fb$^{-1}$. Several exclusive search regions are defined 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 observed yields are compatible with predictions from standard model processes. The results are interpreted in two simplified models of gluino pair production. In a model where each gluino decays to top quarks and a neutralino, gluinos with masses up to 1.65 TeV are excluded for neutralino masses below 600 GeV. In the other 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 1.6 TeV are excluded for neutralino masses below 500 GeV, assuming a chargino with mass midway between the gluino and neutralino masses.
