Search for resonant selectron production in a dielectron and jet final state with CMS at √s = 8 TeV — •Sebastian Thüer, Andreas Güth, Thomas Hebbeker, Arnd Meyer, Philipp Millet, Markus Radziej, Lars Sonnenschein, 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 the conventional SUSY searches.
In the talk the search for resonant selectron production will be presented. In contrast to R-parity conserving models a selectron can be produced resonantly via the R-parity violating coupling λ111′. The final state with two electrons and jets will be analyzed. Standard Model backgrounds are substantially reduced by requiring the two electrons to have the same charge. The search is performed with the 2012 data collected with the CMS experiment corresponding to 19.7 fb−1 at a center-of-mass energy of 8 TeV and the sensitivity is competitive with indirect limits from neutrinoless double beta decay.
