Descripción
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. The data were recorded by the CMS experiment at the LHC and
correspond to an integrated luminosity of 2.3 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 event yields in data are consistent
with the expected backgrounds from standard model processes. The results
are interpreted using two simplified models of supersymmetric particle
spectra, both of which describe gluino pair production. In the first
model, each gluino decays via a three-body process to top quarks and a
neutralino, which is associated with the observed missing transverse
momentum in the event. Gluinos with masses up to 1.6 TeV are excluded
for neutralino masses below 600 GeV. In the second model, each gluino
decays via a three-body process to two light quarks 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 1.4 TeV are excluded for
neutralino masses below 700 GeV.
