The Physics Generators Activity Area is a common forum for discussion and technical work on the physics event generators used by HEP experiments. It promotes the collaboration of experimental and theoretical physicists from different experiments and generator teams and of software and computing engineers, with the aim of having them work together on improving the current codes and production workflows and on making new theoretical advances easier to implement in a computationally efficient way.

The group was set up as a follow-up of the Physics Event Generator Computing Workshop that was held at CERN in November 2018, during which an initial program of work in this area was identified.

The mailing list for all WG members is hsf-generator-wg@googlegroups.com. If you would like to subscribe to this group, please click on https://groups.google.com/group/hsf-generator-wg/subscribe or send an email to hsf-generator-wg+subscribe@googlegroups.com
