Contribution
This release introduces several improvements and new models, notably in parton shower evolution, colour reconnection, and BSM support, advancing the accuracy and flexibility of event simulation.
Findings
Improved simulation of multiple-parton interactions and diffractive processes.
Enhanced modeling of baryonic colour re-connection.
Support for generic Lorentz structures in BSM models.
Abstract
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.
