R-Parity violating minimal supergravity at the LHC

Understand

We consider the case where supersymmetry with broken R-parity is embedded in the minimal supergravity model (mSUGRA).

• This alters the standard mSUGRA spectrum and opens a wide range in parameter space, where the scalar tau is the lightest supersymmetric particle, instead of the lightest neutralino.
• We study the resulting LHC phenomenology.
• Promising signatures would be detached vertices from long-lived staus, multi lepton final states and multi-tau final states.
