form of supersymmetry in hadronic
final states and missing
transverse energy (ET) using a dataset of 35.9 fb−1 collected
during the 2016 proton-proton runs by the Compact Muon Solenoid
(CMS) detector
at the Large Hadron Collider (LHC). The search uses
robust kinematic variables
to suppress backgrounds while
maintaining good acceptance to a broad range
of signal models and
employs data-driven techniques to accurately determine
backgrounds
and systematic uncertainties. No evidence for Beyond Standard
Model (BSM) physics is observed and simplified models are used to
interpret the
results. For gluino mediated models, the gluino mass
up to 1850 GeV and the
lightest symmetric particle (LSP) up to
1100 GeV are excluded. For light squark
mediated models, the light
squark mass up to 1350 GeV (700 GeV) and the LSP
up to 650 GeV
(400 GeV), assuming no degeneracy in the light squark masses (a
degeneracy in light squark masses). For sbottom mediated models,
the sbottom
mass is excluded to 1075 GeV and the LSP mass up to
550 GeV. For stop mediated
models, the stop mass is excluded up to
1075 GeV with the LSP mass up to 400 GeV.Read More
