| Summary: | Results are reported from a search for supersymmetric particles in the final
state with multiple jets and large missing transverse momentum. The search uses a sample
of proton-proton collisions at √
s = 13 TeV collected with the CMS detector in 2016–2018,
corresponding to an integrated luminosity of 137 fb−1
, representing essentially the full LHC
Run 2 data sample. The analysis is performed in a four-dimensional search region defined
in terms of the number of jets, the number of tagged bottom quark jets, the scalar sum of
jet transverse momenta, and the magnitude of the vector sum of jet transverse momenta.
No significant excess in the event yield is observed relative to the expected background
contributions from standard model processes. Limits on the pair production of gluinos and
squarks are obtained in the framework of simplified models for supersymmetric particle
production and decay processes. Assuming the lightest supersymmetric particle to be a
neutralino, lower limits on the gluino mass as large as 2000 to 2310 GeV are obtained at
95% confidence level, while lower limits on the squark mass as large as 1190 to 1630 GeV
are obtained, depending on the production scenario |
