PyHEP 2021

The PyHEP 2021 workshop was held as a virtual workshop on 5-9 July 2021.


Run for the second consecutive year as an event online, it attracted approximately 1300 registrants from a very broad spectrum of communities from the LHC to neutrinos and astroparticle physics, including undergraduates and early-career graduates. Presentations and captioned recordings are available from the Indico agenda.


We organise many activities, from our working groups, to organising events, to supporting projects as HSF projects, and helping communication within the community through our discussion forums and technical notes.

The HSF can also write letters of collaboration and cooperation to project proposals.
