Spontaneous R-Parity Breaking and Left-Right Symmetry

TL;DR

This paper introduces a minimal left-right symmetric model where R-parity is spontaneously broken via sneutrino VEVs, generating neutrino masses and predicting testable collider signatures without the Majoron problem.

Contribution

It presents a renormalizable model linking R-parity breaking and left-right symmetry, with predictions for collider phenomenology based on SUSY breaking scales.

Findings

R-parity and gauge symmetry are broken by sneutrino VEVs.

The model predicts specific signatures in neutralino, chargino, Z', and W_R decays at the LHC.

No Majoron problem arises in this framework.

Abstract

We propose a simple renormalizable left-right theory where R-parity is spontaneously broken and neutrino masses are generated through the Type I seesaw mechanism and R-parity violation. In this theory R-parity and the gauge symmetry are broken by the sneutrino vacuum expectation values and there is no Majoron problem. The SU(2)_R and R-parity violation scales are determined by the SUSY breaking scale making the model very predictive. We discuss the spectrum and possible tests of the theory through the neutralinos, charginos, Z^' and W_R decays at the Large Hadron Collider.
