On the Origin of R-parity Violation in Supersymmetry

TL;DR

This paper argues that R-parity, a symmetry in supersymmetric theories, is likely spontaneously broken at the SUSY scale due to local B-L symmetry, impacting collider search strategies.

Contribution

It demonstrates that the simplest B-L based supersymmetric models naturally lead to R-parity violation at the SUSY scale.

Findings

R-parity is predicted to be spontaneously broken in minimal B-L models

Implications for LHC searches are significant and should be reconsidered

Provides theoretical motivation for R-parity violation in supersymmetry

Abstract

The fate of R-parity in supersymmetric theories is discussed in detail. We make a strong case for R-parity violation showing that the simplest theories based on the local B-L symmetry predict the spontaneous breaking of R-parity at the SUSY scale. The possible implications for the searches at the Large Hadron Collider are discussed.
