Soft and diffractive scattering

arXiv:1710.10925
KA-TP-36-2017
MCnet-17-18

by: Gieseke, Stefan (KIT, Karlsruhe, TP) et al.

Abstract:
A model for soft and diffractive scattering is presented which is incorporated seamlessly into the pre-existing MPI model in the Monte Carlo Event Generator Herwig. With the improved model we are able to describe general aspects of Minimum Bias and Underlying Event data.

Baryon production from cluster hadronisation

by: Gieseke, Stefan (KIT, Karlsruhe, TP) et al.

Abstract:
We present an extension to the colour reconnection model in the Monte Carlo event generator Herwig to account for the production of baryons and compare it to a series of observables for soft physics. The new model is able to improve the description of charged-particle multiplicities and hadron flavour observables in pp collisions.

A new model for soft interactions in Herwig

KA-TP-14-2017
MCNET-17-03
arXiv:1704.00911
Acta Phys.Polon. B48 (2017) 1025

by: Gieseke, Stefan (KIT, Karlsruhe, TP) et al.

Abstract:
We present a new model for soft interactions in the Monte Carlo event-generator Herwig. The soft diffractive final states are modeled on the basis of the cluster hadronization model and interactions between soft particles are modeled as multiple particle production with multiperipheral kinematics. We further present much improved results of mininum-bias measurements at different energies.
