A new release of the Monte Carlo event generator Herwig (version 7.2) is now available. This version introduces a number of improvements, notably: improvements to the simulation of multiple-parton interactions, including diffractive processes; a new model for baryonic colour re-connection; spin correlations in both the dipole and angular-ordered parton showers; improvements to strangeness production; an improved choice of evolution variable in the angular-ordered parton shower; support for generic Lorentz structures in BSM models..

Parton Shower and Matching Uncertainties in Top Quark Pair Production with Herwig 7 / Cormier, Kyle (Toronto U.) ; Plätzer, Simon (Vienna U.) ; Reuschle, Christian (Florida State U. ; Lund U., Dept. Theor. Phys.) ; Richardson, Peter (CERN ; Durham U., IPPP) ; Webster, Stephen (Durham U., IPPP)
We evaluate the theoretical uncertainties in next-to-leading order plus parton shower predictions for top quark pair production and decay in hadronic collisions. Our work is carried out using the Herwig 7 event generator and presents an in-depth study of variations in matching schemes with two systematically different shower algorithms, the traditional angular-ordered and alternative dipole shower.

Spin Correlations in Parton Shower Simulations / Richardson, Peter (CERN ; Durham U., IPPP) ; Webster, Stephen (Durham U., IPPP)
Spin correlations are an important, but often neglected, effect in modern Monte Carlo event generators. We show that they can be fully incorporated in Herwig 7 using the algorithm originally proposed by Collins and Knowles in all stages of the event generation process and between the different stages of the event generation.

Reweighting Parton Showers / Bellm, Johannes (Durham U., IPPP ; Durham U.) ; Plätzer, Simon (Durham U., IPPP ; Durham U. ; Manchester U.) ; Richardson, Peter (Durham U., IPPP ; Durham U. ; CERN) ; Siódmok, Andrzej (CERN ; Cracow, INP) ; Webster, Stephen (Durham U., IPPP ; Durham U. ; CERN)
We report on the possibility of reweighting parton-shower Monte Carlo predictions for scale variations in the parton-shower algorithm. The method is based on a generalization of the Sudakov veto algorithm. [...]
