We study a bino-like light neutralino ($\tilde \chi_1^0$) produced at the LHC from the decay of a scalar lepton ($\tilde e_L$) through the process $pp\to \tilde e_{L} \to e\tilde \chi_1^0$ in the context of R-parity-violating (RPV) supersymmetry where $\tilde \chi_1^0$ is the lightest supersymmetric particle. For small masses and RPV couplings, the neutralino is naturally long-lived and its...

We present the recast and sensitivity projection in a large number of benchmark models, significantly extending the physics scope of the recent search for LLPs using the CMS endcap muons detector (https://arxiv.org/abs/2107.04838). The search uses the endcap muon detectors as sampling calorimeter to identify displaced showers produced by decays of long-lived particles (LLPs). The exceptional...

Using ATLAS data from LHC Runs 2 and 3, we propose a search sensitive to pair-production of long-lived sleptons, resulting in final state pairs of displaced and delayed light leptons (e-e, e-$\mu$, and $\mu$-$\mu$). The ATLAS Run 3 trigger menu includes novel displaced electron and muon triggers based on Large Radius Tracking (LRT), a special tracking pass dedicated to displaced tracks, which...
