Description:
Multi-purpose event generator for high energy physics
Herwig++ is a completely new event generator, written in C++. It is built on the experience gained with the well-known event generator HERWIG. The aim is to provide a multi purpose event generator with similar or improved capabilities (like angular ordered parton evolution and the cluster hadronization model). . This package provides program files and run-time libraries of Herwig++.
