Abstract
We study the supersymmetrized version of the singlet majoron model and, performing an analysis of the renormalization group equation improved potential, we find that a spontaneous breaking of -parity can be achieved for a wide range of the parameters. Studying the finite temperature effective potential, we show that the phase transition leading to -parity breaking can be of the first order and can occur at temperatures below the weak scale, thus avoiding any constraint coming from the requirement of the preservation of the baryon asymmetry in the early Universe.
