The Higgs sector of a supersymmetric left-right model

We study the symmetry breaking sector of a supersymmetric left-right model based on the gauge group $SU(2)_L\times SU(2)_R\times U(1)_{B-L}$. The explicit mass matrices of neutral, singly charged and doubly charged scalars are constructed. In the minimum the $R$-parity is found to be spontaneously broken. An experimentally interesting feature of the model is that one of the doubly charged scalars is possibly light enough to be seen in the next linear collider.
