Search for resonant slepton production in a dilepton and jet final state with CMS — •Sebastian Thüer, Andreas Güth, Thomas Hebbeker, Arnd Meyer, Philipp Millet, Markus Radziej, and Daniel Teyssier — III. Physikalisches Institut A, RWTH Aachen

In many supersymmetric scenarios R-parity is assumed to be conserved. However, abandoning R-parity conservation can result in a variety of new and interesting final states, some of which are not covered by conventional SUSY searches.

In the talk the search for resonant slepton production will be presented. In contrast to R-parity conserving models a single slepton can be resonantly produced. First and second generation slepton production via one of the two R-parity violating couplings λ₁₁₁^′ or λ₂₁₁^′ is searched for. The final states with either two electrons or two muons and additional jets are analysed. Standard Model backgrounds are substantially reduced by requiring the two leptons to have the same charge. All particles can be reconstructed allowing the measurement of the involved sparticle masses, which can be used to further separate a potential signal from the background.

Results from Run I are shown which can compete with indirect limits from neutrinoless double beta decay and leptonic pion decays.
