The Fate of Long-Lived Superparticles with Hadronic Decays after LHC Run 1

Understand

Supersymmetry searches at the LHC are both highly varied and highly constraining, but the vast majority are focused on cases where the final-stage visible decays are prompt.

• Scenarios featuring superparticles with detector-scale lifetimes have therefore remained a tantalizing possibility for sub-TeV SUSY, since explicit limits are relatively sparse.
• Nonetheless, the extremely low backgrounds of the few existing searches for collider-stable and displaced new particles facilitates recastings into powerful long-lived superparticle searches, even for models for which those searches are highly non-optimized.
• In this paper, we assess the status of such models in the context of baryonic R-parity violation, gauge mediation, and mini-split SUSY.
