MCnet is an international community of high-energy physics theorists, experimentalists, and software developers behind the leading techniques and tools for simulating fully exclusive particle-collision events.

MCnet members are responsible for the leading shower+hadronisation event-generator code families Herwig, Pythia, MadGraph/aMC@NLO, and Sherpa, key to particle-physics experiments including those at the CERN Large Hadron Collider. Find out more about us.

Previously the MCnetITN3 EU Innovative Training Network, MCnet is now an umbrella community for all working in methods, codes, and applications of general-purpose MC event generators. We coordinate interoperability of tools, support the experiment and phenomenology physics communities, and provide training and community events including workshops, meetings and summer schools.

GGI 2027: Precision Theory, Event Simulation and Computing

21 June - 23 July 2027 | Galileo Galilei Institute, Florence

MCnet will host a five-week programme at the Galileo Galilei Institute (GGI) in Florence in summer 2027, bringing together researchers working across scattering amplitudes, resummation, Monte-Carlo event generation, high-performance computing, machine learning, and experimental collider physics.

The programme will explore the theoretical and computational challenges of achieving precision collider physics in the HL-LHC era, with a particular focus on the interfaces between fundamental theory, numerical methods and realistic event-level predictions.

Further details, including the programme schedule and information on participation, will be announced in due course.

Save the date: 21 June – 23 July 2027, Florence.

Deepak Kar, 1979-2025

MCnet was shocked and sad to hear of the untimely passing of our good friend and colleague Deepak Kar, who died shortly after contracting malaria before Christmas 2025. Deepak had a long-term association with MC modelling and QCD measurements, from early work on underlying event measurements to more recent collaborations with MCnet on modelling of “dark QCD” jet physics. Deepak was a much-loved member of the community and an attentive, engaged and inclusive supervisor at Wits University. He will be sorely missed.

Short-term studentships

We are happy to announce short-term MC project placements with MCnet teams, in association with CERN. See our Opportunities page for details and how to apply.
