Search for R-parity violating supersymmetry in dilepton channels

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~$\rm{fb^{-1}}$. 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.
