Resonant Slepton Production Yields CMS eejj and ejj Missing pₜ Excesses

Original · EN

Recent CMS searches for di-leptoquark production report local excesses of 2.4σ in a eejj channel and 2.6σ in a ejj missing pₜ channel. Here, we simultaneously explain both excesses with resonant slepton production in R-parity violating supersymmetry (SUSY). We consider resonant slepton production, which decays to a lepton and a chargino/neutralino, followed by three-body decays of the neutralino/chargino via an R-parity violating coupling. There are regions of parameter space which are also compatible at the 95% confidence level (CL) with a 2.8σ eejj excess in a recent CMS Wᵣ search, while being compatible with other direct search constraints. Phase-II of the GERDA neutrinoless double beta decay (0νββ) experiment will probe a sizeable portion of the good-fit region.
