3D Structure of the Nucleon via Generalized Parton Distributions

Jun 25, 2024, 10:00 AM → Jun 28, 2024, 1:40 PM Asia/Seoul

Mega Star Room B (Howard Johnson Incheon Airport Hotel)

Alexandre Camsonne (Jefferson Laboratory), Hyon-Suk Jo (Kyungpook National University), Kyungseon Joo (University of Connecticut), Kirill Semenov-Tyan-Shanskiy (Kyungpook National University), Hyeon-Dong Son (Inha University)

This workshop aims to review the present status of studies of the 3D structure of the nucleon via generalized parton distributions (GPDs) and formulate a plan for future development of the field. Particular emphasis will be placed on the formulation of concepts, the role of non-perturbative dynamics in hadron structure, the global analysis of experimental data, and the connection with current and future experimental programs.

 

Topics include:

• GPDs: Experiments at Jefferson Lab 12 GeV, COMPASS, EIC, PANDA, J-PARC, etc.
• GPDs: Theory and Lattice.
• GPDs: Global Analysis and Machine Learning.
• Path forward: Strategy for theory and experiment. Planning of White Paper.collaborations.

 

This is an in-person meeting. We do not provide a service for online participation of audience.
