2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/224212We 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.4 pages, minor corrections, title changed, to appear in Physics Letters BHigh Energy Physics - PhenomenologyHigh Energy Physics - Experimenttext
