TL;DR

This paper develops a Monte Carlo simulation for R-parity violating supersymmetric processes, incorporating colour coherence effects and implementing them in the HERWIG generator to improve modeling accuracy.

Contribution

It introduces a detailed simulation framework for R-parity violating SUSY processes, including decay matrix elements and production mechanisms, with implementation in HERWIG.

Findings

Simulated R-parity violating decay and production processes with colour coherence.

Implemented these processes in the HERWIG Monte Carlo generator.

Provided detailed matrix elements for key SUSY decay and production channels.

Abstract

We study the colour connection structure of R-parity violating decays and production cross sections, and construct a Monte Carlo simulation of these processes including colour coherence effects. We then present some results from the implementation of these processes in the HERWIG Monte Carlo event generator. We include the matrix elements for the two-body sfermion and three-body gaugino and gluino decays as well as the two-to-two resonant hard production processes in hadron-hadron collisions.
