## Abstract

We obtain a relation between right-handed gauge boson mass and soft squark mass in naturally R-parity conserving general supersymmetric left-right models. This relation implies that either WR is lighter than twice the soft squark mass, or a ratio of vacuum expectation values (VEVs) in the model, denoted by tan a, is close to its value of unity in the limit of vanishing D-terms. Generally, we find that for heavy WR tan a is larger than one, and that the right-handed sneutrino VEV, responsible for spontaneous R-parity breaking, is at most of the order M_{SUSY}/h_{Δ}_{ R}, where M_{SUSY} is supersymmetry breaking scale and h_{Δ}_{ R} is the Yukawa coupling in Majorana mass term for right-handed neutrinos. These constraints follow from SU(3)_{c} and U(1)_{em} gauge invariance of the ground state of the theory.
