Abstract:

A data sample of events from proton-proton collisions with two isolated same-sign leptons or at least three leptons, and at least two jets, is studied in a search for signatures of new physics phenomena by the CMS Collaboration at the LHC. The data correspond to an integrated luminosity of

137~\mathrm{fb}^{-1}

, at a center-of-mass energy of

13~\mathrm{TeV}

. The properties of the events are consistent with expectations from standard model processes, and no excess yield is observed. Exclusion limits at

95\%

confidence level are set on cross sections for the pair production of gluinos or squarks for various decay scenarios in the context of supersymmetry models conserving or violating R-parity. The observed lower mass limits are as high as

2.1~\mathrm{TeV}

for gluinos, and

0.9~\mathrm{TeV}

for top and bottom squarks.

Note:

Preliminary results

p p: scattering
p p: colliding beams
gluino: pair production
squark: pair production
stop: pair production
sbottom: pair production
new physics: signature
R parity: violation
