R-parity Violation and Phenomenological Constraints

Abstract

We have seen in the previous chapter that the general renormalizable supersymmetric extension of the standard model allows also baryon and lepton number violating interactions. These interactions, called the R-parity violating interactions, can be avoided by imposing the conservation of R-parity. This assumption is however ad hoc and must be investigated phenomenologically. In this chapter, we will first review the R-parity violating interactions and their properties. We will then present briefly the bilinear R-parity violation, and finally list the phenomenological constraints on the trilinear R-parity violation given by particle physics experiments.
