Workshop on Double Parton Scattering and the 3D structure of hadrons

11 Jan 2025, 19:00 → 15 Jan 2025, 14:00 Europe/Zurich

Aussois, Centre Paul Langevin

Jean-Philippe Lansberg (Université Paris-Saclay (FR)), Matteo Rinaldi

This purpose of this workshop is to bring together theoretical and experimental experts in Double Parton Scattering (DPS) and possible related areas, such exclusive, inclusive, semi-inclusive and diffractive processes aimed to obtain novel information on the partonic structure of nucleons and nuclei. By focusing on insights gained from high-energy processes, the workshop seeks to update the community and foster collaboration and synergy among research groups.

 

The workshop will be 3 1/2 day long with 3 full day (Sunday, Monday and Tuesday) and a summary session on Wednesday morning. Participants are expected to reach on Saturday January 11, 2025 (Welcome drink at 19h) and depart on Wednesday January 15, 2025 after lunch.
