Abstract: Signatures of supersymmetry with $R$ -parity violation (RPV) are searched for using proton-proton collisions at a centre-of-mass energy of 8 TeV. The analysis is based on the 2012 dataset taken with the CMS detector, corresponding to an integrated luminosity of 19.7 fb $^{-1}$ . Final states consisting of two isolated leptons (electrons or muons) and jets are analyzed and interpreted in models of resonant slepton production via the RPV couplings $\lambda^{\prime}_{111}$ and $\lambda^{\prime}_{211}$ . The observation is in agreement with the expectation from standard model processes. Within modified versions of the cMSSM, including one of the two couplings as an additional non-zero parameter, exclusion limits on these couplings are set in the range of scalar masses $m_0$ up to 1.5 TeV and gaugino masses $m_{1/2}$ up to 2.5 TeV. Using simplified models, limits on the production cross section in the $m_{\widetilde{\ell}}$ - $m_{\widetilde{\chi}_{1}^{0}}$ mass plane are determined.
