| Abstract: This note presents a search for new physics using single-lepton events with high multiplicity of jets and b-tagged jets, without a requirement on missing transverse momentum. The analysis is based on proton-proton collision data collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 fb$ ^{-1} $. It is sensitive to $ R $-parity violating supersymmetry models, where supersymmetric particles can decay into standard model particles through interactions that violate baryon number conservation. In particular, the target model is gluino pair production where each gluino decays to top, bottom, and strange quarks. The sum of large-radius jet masses is used to distinguish the signal from background. No significant excess over the background is observed, and constraints are placed on the parameter space of gluino mass. Such gluinos with a mass of 1890 GeV are excluded at 95% confidence level. | ||
