Abstract

We construct the truly minimal left-right symmetric model by utilizing only the fields dictated by supersymmetry and automatic R-parity conservation. Allowing for non-renormalizable operators in the superpotential, we show that parity can be spontaneously broken while preserving electromagnetic gauge invariance. The scale of parity breakdown is predicted in the intermediate region: MR > 1010 - 1011 GeV, and R-parity remains exact. The theory contains a number of charged and doubly charged Higgs scalars with a low mass of order MR2/MPlanck, accessible to experiment.
