Descripción
Results are presented from a search for supersymmetry in events with a
single electron or muon and hadronic jets. The data correspond to a
sample of proton-proton collisions at √{ s } = 13TeV with an
integrated luminosity of 35.9fb-1, recorded in 2016 by the
CMS experiment. A number of exclusive search regions are defined
according to the number of jets, the number of b -tagged jets, the
scalar sum of the transverse momenta of the jets, and the scalar sum of
the missing transverse momentum and the transverse momentum of the
lepton. Standard model background events are reduced significantly by
requiring a large azimuthal angle between the direction of the lepton
and of the reconstructed W boson, computed under the hypothesis that all
of the missing transverse momentum in the event arises from a neutrino
produced in the leptonic decay of the W boson. The numbers of observed
events are consistent with the expectations from standard model
processes, and the results are used to set lower limits on
supersymmetric particle masses in the context of two simplified models
of gluino pair production. In the first model, where each gluino decays
to a top quark-antiquark pair and a neutralino, gluino masses up to 1.8
TeV are excluded at the 95% CL. The second model considers a three-body
decay to a light quark-antiquark pair and a chargino, which subsequently
decays to a W boson and a neutralino. In this model, gluinos are
excluded up to 1.9 TeV.
