Parton-shower simulations of R-parity violating supersymmetric models

We study the colour connection structure of R-parity violating decays and p roduction cross sections, and construct a Monte Carlo simulation of these p rocesses including colour coherence effects. We then present some results f rom the implementation of these processes in the HERWIG Monte Carlo event g enerator. We include the matrix elements for the two-body sfermion and thre e-body gaugino and gluino decays as well as the two-to-two resonant hard pr oduction processes in hadron-hadron collisions.
