Description
A search for new physics is carried out in events with at least three
electrons or muons in any combination, jets, and missing transverse
momentum. Results are based on the sample of proton-proton collision
data produced by the LHC at a center-of-mass energy of 13 TeV and
collected by the CMS experiment in 2016. The data sample analyzed
corresponds to an integrated luminosity of 35.9 fb-1. Events
are classified according to the number of b jets, missing transverse
momentum, hadronic transverse momentum, and the invariant mass of
same-flavor dilepton pairs with opposite charge. No significant excess
above the expected standard model background is observed. Exclusion
limits at 95% confidence level are computed for four different
supersymmetric simplified models with pair production of gluinos or
third-generation squarks. In the model with gluino pair production, with
subsequent decays into a top quark-antiquark pair and a neutralino,
gluinos with masses smaller than 1610 GeV are excluded for a massless
lightest supersymmetric particle. In the case of bottom squark pair
production, the bottom squark masses are excluded up to 840 GeV for
charginos lighter than 200 GeV. For a simplified model of heavy top
squark pair production, the \tilde{t}_2 mass is excluded up to 720, 780,
or 710 GeV for models with an exclusive \tilde{t}_2\to \tilde{t}_1H
decay, an exclusive \tilde{t}_2\to \tilde{t}_1Z decay, or an equally
probable mix of those two decays. In order to provide a simplified
version of the analysis for easier interpretation, a small set of
aggregate signal regions also has been defined, providing a compromise
between simplicity and analysis sensitivity.
