Hi, I was going through the concept of R parity in SUSY. In the case of SUSY we do not have Baryon and Lepton number conservation instead we have R parity conservation defined by, R-parity= (-1)^2s+3B+L which is required for the proton to be stable. But it has been found that this condition need not be satisfied for proton stability. Instead we can have either Lepton number or Baryon number conserving terms in the Lagrangian which serves the purpose. My question is- 'There are so many SUSY models and so can we have any model to be R parity conserving or violating by the same recipe'? Thanks.
