ABSTRACT
It is well known that the baryon and lepton numbers, В and L, respectively, are conserved in the Standard Model (SM) of particle physics. In the minimal supersymmetric standard model (MSSM) this is not the case, and the В and L conservation are often imposed on the model by the so-called R-parity [1] conservation,
where Rp is +1 for Standard Model particles and -1 for their superpartners. On the other hand, the supersymmetry and gauge symmetry alone allow
also Rp breaking terms [2]
with \ į j k = —Хјгк and \ ” -к — —X"kj· Thus there are 45 new supersymmet ric parameters in the model compared to the MSSM.
