From initial gluons to hydrodynamics: Gluons inside hadrons and their thermalization

24 oct. 2022, 09:30 → 25 oct. 2022, 19:00 Europe/Paris

Institut Pascal

Cyrille Marquet (CPHT - Ecole Polytechnique), Francesco Bossu (CEA-Saclay), Jean-Yves Ollitrault (IPhT Saclay), Michael Winn (DPhN/IRFU/DRF/CEA Paris-Saclay)

The goal of this workshop is to progress on the question to which extent the physics studies of the initial state of heavy-ions can be related to hadron structure physics as well as how the initial state in hadron collisions relaxes into a hydrodynamic description.
