Reconciling Supersymmetry and Left-Right Symmetry
Abstract
We construct the minimal supersymmetric left-right theory and show that at the renormalizable level it requires the existence of an intermediate
B−L
breaking scale. The subsequent symmetry breaking down to MSSM automatically preserves R-symmetry. Furthermore, unlike in the nonsupersymmetric version of the theory, the see-saw mechanism takes its canonical form. The theory predicts the existence of a triplet of Higgs scalars much lighter than the
B−L
breaking scale.
