摘要：

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