Soft Interactions in Herwig

Abstract

We introduce a new model for soft interactions in the Monte Carlo event generator Herwig. We add a new model for the simulation of diffractive final states, based on the cluster hadronization model in Herwig. The soft component of the Multiple partonic interaction model is replaced by a refined model for soft gluon production. With these two components we are for the first time able to give a full simulation of minimum-bias events at hadron colliders. We briefly describe the models and present a few results obtained with it.
