Simulations of R-parity Violating SUSY Models

Abstract

In recent years there has been a great deal of interest in R-parity violating supersymmetric models. We explain the motivation for studying these models and explore the various phenomenological consequences of R-parity violation. It has become essential for the experimental study of any new model to have a Monte Carlo event generator which includes the processes predicted by that model. We review the techniques used in the construction of these simulations and show how we have extended the HERWIG event generator to include R-parity violating processes. We discuss how to treat the emission of QCD radiation in these processes including colour coherence effects via the angular-ordered parton shower. We then make use of this simulation to investigate the discovery potential for resonant slepton production, via either supersymmetric gauge or R-parity violating decay modes, in hadron-hadron collisions. Finally, we look at the possibility that the KARMEN time anomaly can be explained by the existence of a light neutralino which is produced and decays via R-parity violation.
