Boosting Searches for Natural SUSY with RPV via Gluino Cascades

Understand

In the presence of even minuscule baryonic R-parity violation, the stop can be the lightest superpartner and evade LHC searches because it decays into two jets.

• In order to cover this interesting possibility, we here consider new searches for RPV stops produced in gluino cascades.
• While typical searches for gluinos decaying to stops rely on same-sign dileptons, the RPV cascades usually have fewer hard leptons, less excess missing energy, and more jets than R-parity conserving cascades.
• If the gluino is a Dirac fermion, same-sign dilepton signals are also often highly depleted.
