Explaining a CMS $eejj$ Excess With $\mathcal{R}-$parity Violating Supersymmetry and Implications for Neutrinoless Double Beta Decay

Understand

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 $m_{eejj} \sim 2$ 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 $\mathcal{R}-$parity violating coupling.
