Search for light stop RPV supersymmetry with three or more leptons and b-tags

We present a search for anomalous production of events with three or more isolated leptons and at least one bottom-quark jet produced in $pp$ collisions at $\sqrt{s} = 8$ TeV. We analyze 19.5 $\textrm{fb}^{-1}$ of data collected by the CMS experiment during the 2012 LHC run. No excesses above the standard model expectations are observed. We interpret the search results in the context of supersymmetric models with diminished missing transverse energy signatures arising from light stop pair production with $R$-parity-violating decays of the lightest supersymmetric particle.
