The Herwig Event Generator¶
Herwig is a multi-purpose particle physics event generator.
It is built based on the experience gained with both the HERWIG 6 and Herwig++ 2 event generators. Continuing the Herwig++ 2 development, Herwig 7.0 (Herwig++ 3.0) replaces any prior HERWIG or Herwig++ versions.
Herwig provides significantly improved and extended physics capabilities when compared to both its predecessors, HERWIG 6 and Herwig++ 2, while keeping the key model motivations such as coherent parton showers (including angular-ordered and dipole-based evolution), the cluster hadronization model, an eikonal multiple-interaction model, highly flexible BSM capabilities and improved perturbative input using next-to-leading order QCD.
Download and Installation
The current version is Herwig 7.2.1, and is based on ThePEG 2.2.1
Installing and using the current version is extensively covered in the tutorials. A detailed manual covering all physics developments since Herwig++ 2 is in preparation.
The detailed Herwig++ 2 manual is arXiv:0803.0883. When using Herwig 7, please cite this manual along with the Herwig 7 release note (Eur.Phys.J. C76 (2016) no.4, 196) until the main Herwig 7 manual is available. The release note describes the new features of the latest version, 7.2.
