Search for R-parity-violating SUSY in final states with zero or one lepton and large multiplicity of jets and b-tagged jets

Preliminary results are reported from a search for physics beyond the standard model in proton-proton collisions at $\sqrt{s}=13$~TeV, focusing on the signature of large multiplicity of jets and b-tagged jets, in a final state with zero or one reconstructed lepton. The data sample corresponds to an integrated luminosity of 2.7~fb$^{-1},$ recorded by the CMS experiment at the Large Hadron Collider. The results are interpreted in terms of limits on the parameter space for the $R$-parity-violating supersymmetric extension of the standard model in a benchmark model of gluino pair production where each gluino decays via $\widetilde{\rm g} \rightarrow {\rm tbs}$. Assuming the gluino decays solely to tbs, gluino masses smaller than 1360~GeV are excluded at a 95\% confidence level.
