Abstract: The PYTHIA program can be used to generate high-energy-physics -events- withsets of outgoing particles produced in the interactions between two incomingparticles. The objective is to provide a representation, as accurate aspossible, of event properties in a wide range of reactions. One such reaction,that is not well understood is Diffraction. Among the several alternativeapproaches that have been proposed, in PYTHIA, we follow a fairly conventionalPomeron based one, but fully integrated to use the standard PYTHIA machineryfor multiple interactions, parton showers and hadronization. This note reportsthe development in PYTHIA in the way diffraction is modeled without providingspecific details for usage. Results are compared with an alternative eventgenerator called PHOJET. The code and further information may be found on thePythia web page: this http URL
