Explaining the CMS eejj Excess With R−parity Violating Supersymmetry and Implications for Neutrinoless Double Beta Decay
The recent CMS searches 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 an excess around meejj ~ 2 TeV. In this work, we explain the reported CMS excess with Rparity violating supersymmetry (SUSY).We consider the resonant slepton and sneutrino production, followed by the three body decays of neutralino and chargino via R-parity violating coupling. These fit the excess for slepton and sneutrino masses around 2 TeV. This scenario can further be tested in neutrinoless double beta decay experiment (0νββ). GERDA Phase-II will probe a significant portion of the good-fit parameter space.
