Monte Carlo Implementations of Diffraction at HERA

Abstract

The Monte Carlo implementation of different approaches for diffractive scattering in $e-p$ collisions (resolved $\text{PO}$, pQCD, soft color interactions) is described, with emphasis on the construction of the hadronic final state. Simple models for proton dissociation and exclusive vector meson production are described. A comparison of the different approaches is given.
