Sensitivity study of resonant tau-sneutrino production in the e mu final state at $\sqrt{s}$ = 13 TeV at CMS

This thesis is done in preparation of an analysis for future resonant τ-sneutrino searches with an electron and a muon in its final state in proton-proton collisions at the LHC at CERN with a center-of-mass energy of 13 TeV and a luminosity of 1 fb−1. The underlying theory for this search is the theory of supersymmetry with R-parity violation. As backgrounds, the Diboson backgrounds, the t¯t background, the tW background and the Drell-Yan background are relevant and taken from Monte Carlo. Additionally, the jet background is considered and estimated in this work. With signal samples from Monte Carlo, the mass resolution and efficiencies are determined for 13 TeV data. At the end, a expected limit is set for the τ-sneutrino mass.
