Description

The Next to Minimal Supersymmetric Standard Model (NMSSM) with singlino-like neutralino as the lightest supersymmetric particle (LSP) can open up possibilities for long-lived electroweakinos. We identify such regions in the NMSSM parameter space where the next to lightest supersymmetric particle (NLSP) is a long-lived bino-like electroweakino, consistent with dark matter direct detection and collider constraints. These long-lived NLSPs can appear as displaced vertex signatures in the cascade decay of directly produced chargino-neutralino pairs at the high luminosity LHC (HL-LHC). We study the prospects of observing such scenarios at the HL-LHC through track-based analysis. We show that the discovery reach of the HL-LHC on the eletroweakino parameter space can be improved through focused long-lived particle searches.
