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.

• If you're going to include an $SU(2)_R$ , then your $U(1)$ would more likely be $U(1)_{B-L}$ , for the baryon ( $B$ ) minus lepton ( $L$ ) quantum number, not $U(1)_Y$ , since $I_{3R}$ is already pres [stackexchange, 2 points]
