Phenomenology of a Long-Lived LSP with R-Parity Violation

Understand

We present the leading experimental constraints on supersymmetric models with R-parity violation (RPV) and a long-lived lightest superpartner (LSP).

• We consider both the well-motivated dynamical RPV scenario as well as the conventional holomorphic RPV operators.
• Guided by naturalness, we study the cases of stop, gluino, and higgsino LSPs with several possible leading decay channels in each case.
• The CMS displaced dijet and the ATLAS multitrack displaced vertex searches have been fully recast, with all cuts and vertex reconstruction algorithms applied.
