Displaced Supersymmetry

Understand

The apparent absence of light superpartners at the LHC strongly constrains the viability of the MSSM as a solution to the hierarchy problem.

• These constraints can be significantly alleviated by R-parity violation (RPV).
• Bilinear R-parity violation, with the single operator L H_u, does not require any special flavor structure and can be naturally embedded in a GUT while avoiding constraints from proton decay (unlike baryon-number-violating RPV).
• The LSP in this scenario can be naturally long-lived, giving rise to displaced vertices.
