Description

The first PMG week will be organised from 8 to 12 June 2026 at CERN.

Topics will include:

latest updates on ME and PS generators (MadGraph, Sherpa, Herwig, Pythia, MINNLOPS, ...)
updates and issues on modelling of top/vector boson/Higgs/jets processes
hackathons on software and MC sample requests

Participation to the workshop is free of charge.

A workshop dinner will be held on Wednesday June 10th at Luigia Academy (Meyrin) at 8pm CEST.

Participants should arrange their own travel and accommodation (be aware of spam emails offering travel/accommodation).

If you require a CERN visitor badge, please get in touch with the organising committee.
