Description
Results are reported from a search for supersymmetric particles in
proton-proton collisions in the final state with a single, high
transverse momentum lepton; multiple jets, including at least one
b-tagged jet; and large missing transverse momentum. The data sample
corresponds to an integrated luminosity of 2.3 fb-1 at
√{s}=13 TeV, recorded by the CMS experiment at the LHC. The search
focuses on processes leading to high jet multiplicities, such as gluino
pair production with tilde{g}to toverline{t}{tilde{χ}}_1^0 . The
quantity M J , defined as the sum of the masses of the
large-radius jets in the event, is used in conjunction with other
kinematic variables to provide discrimination between signal and
background and as a key part of the background estimation method. The
observed event yields in the signal regions in data are consistent with
those expected for standard model backgrounds, estimated from control
regions in data. Exclusion limits are obtained for a simplified model
corresponding to gluino pair production with three-body decays into top
quarks and neutralinos. Gluinos with a mass below 1600 GeV are excluded
at a 95% confidence level for scenarios with low {tilde{χ}}_1^0
mass, and neutralinos with a mass below 800 GeV are excluded for a
gluino mass of about 1300 GeV. For models with two-body gluino decays
producing on-shell top squarks, the excluded region is only weakly
sensitive to the top squark mass. [Figure not available: see fulltext.]
