Phenomenology of R-Parity Breaking in E6 Models
  We explore the phenomenology of new R-parity violating operators that can occur in E6 models. The set of allowed operators is found to depend sensitively on the nature of the extension of the standard model gauge group. These new interactions lead to additional production processes for the exotic particles in such models and allow the LSP to decay but with a highly suppressed rate. The implications of these new interations are examined for the Tevatron, SSC, LHC, HERA, and sqrt{s} = 0.5 and 1 TeV e+e- colliders.
