Contribution

The paper develops a novel combined model for soft and diffractive interactions in Herwig, enhancing the simulation accuracy for minimum-bias events at the LHC.

Findings

Improved minimum-bias measurement results at LHC energies.

Effective modeling of diffractive final states.

Enhanced simulation of soft multiple interactions.

Abstract

We present a new model for soft interactions in the event-generator Herwig. The model consists of two components. One to model diffractive final states on the basis of the cluster hadronization model and a second component that addresses soft multiple interactions as multiple particle production in multi- peripheral kinematics. We present much improved results for minimum-bias measurements at various LHC energies.
