Supersymmetry at the LHC and The Theory of R-parity

TL;DR

This paper explores how spontaneous R-parity breaking in supersymmetric models could produce distinctive multilepton signals at the LHC, and discusses cosmological constraints from sterile neutrinos.

Contribution

It introduces a minimal gauge theory for R-parity breaking and analyzes its unique multilepton signatures for LHC detection.

Findings

Multilepton signals can test R-parity breaking models.

Cosmological constraints limit sterile neutrino properties.

Potential impact on supersymmetry searches at the LHC.

Abstract

We discuss the possible signatures at the Large Hadron Collider in models where R-parity is spontaneously broken. In the context of the minimal gauge theory for R-parity, we investigate signals with multileptons which can provide an unique test of this theory. The possible impact of these ideas for the search of supersymmetry at the Large Hadron Collider is discussed. We also discuss the constraints coming from cosmology due to the existence of two light sterile neutrinos in the theory.
