JuliaHEP

JuliaHEP is an informal organization that aims to unify effort in developing Julia projects related to high energy physics.

JuliaHEP Workshops

We organise annual workshops for the JuliaHEP community. These are a great place to present new projects and updates.

Our next workshop will be in Munich, at MPI, from 19-23 October 2026:

• JuliaHEP Workshop 2026 at MPI Munich

Our previous workshops have been:

• JuliaHEP Workshop 2025 at Princeton
• JuliaHEP Workshop 2024 at CERN
• JuliaHEP Workshop 2023 at ECAP (Erlangen Centre for Astroparticle Physics)

JuliaHEP Topical Meetings

We organise occasional topical meetings on subjects of interest to the JuliaHEP community - this can be a presentation on a new package, an update, or discussion of an interesting problem.

• JuliaHEP Topical Meeting Calendar

You are very welcome to propose a topic, just contact the JuliaHEP conveners.

Where to find us?

• Many of us are pretty active on the #hep channel of the official Julia Slack workspace.
• For usage or language related questions, you should post to the official Julia Discourse forum with the hep tag.
• Low-frequency communication (e.g. annoucement) also happens on Julia-HEP Google Group, the group is currently public.
• You can find our projects on Github, most hosted under the name-sake JuliaHEP organization.

HSF Working Group

JuliaHEP is also one of the activities of the HEP Software Foundation (HSF). All conveners of the working group can be reached at hsf-juliahep-organisation@googlegroups.com.
