Minimal Supersymmetric Left-Right Model

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: $M_R>{10}^{10}-{10}^{11}GeV$, and R-parity remains exact. The theory contains a number of charged and doubly charged Higgs scalars with a low mass of order $M_R^2\mathrm{/}{M}_{Planck}$, accessible to experiment.
