Abstract

A recent CMS search for the right handed gauge boson WR reports an interesting deviation from the Standard Model. The search has been conducted in the eejj channel and has shown a 2.8σ excess around meejj∼2 TeV. In this work, we explain the reported CMS excess with R-parity violating supersymmetry (SUSY). We consider resonant selectron and sneutrino production, followed by the three body decays of the neutralino and chargino via an Rparity violating coupling. We fit the excess for slepton masses around 2 TeV. The scenario can further be tested in neutrinoless double beta decay (0νββ) experiments. GERDA Phase-II will probe a significant portion of the good-fit parameter space.
