Descripción
A search for supersymmetry is presented based on proton-proton collision
events containing identified hadronically decaying top quarks, no
leptons, and an imbalance pTmiss in transverse
momentum. The data were collected with the CMS detector at the CERN LHC
at a center-of-mass energy of 13 TeV, and correspond to an integrated
luminosity of 35.9 fb-1 . Search regions are defined in terms
of the multiplicity of bottom quark jet and top quark candidates, the
pTmiss , the scalar sum of jet transverse momenta,
and the mT 2 mass variable. No statistically significant
excess of events is observed relative to the expectation from the
standard model. Lower limits on the masses of supersymmetric particles
are determined at 95% confidence level in the context of simplified
models with top quark production. For a model with direct top squark
pair production followed by the decay of each top squark to a top quark
and a neutralino, top squark masses up to 1020 GeV and neutralino masses
up to 430 GeV are excluded. For a model with pair production of gluinos
followed by the decay of each gluino to a top quark-antiquark pair and a
neutralino, gluino masses up to 2040 GeV and neutralino masses up to
1150 GeV are excluded. These limits extend previous results.
