CNF Generalized Parton Distributions and Global Analysis

Jun 12, 2023, 8:00 AM → Jun 14, 2023, 6:00 PM US/Eastern

CEBAF Auditorium (Jefferson Lab Center for Nuclear Femtography)

Marie BOER (Virginia Tech), Latifa Elouadrhiri (Jefferson Lab), Brandon Kriesten (Center for Nuclear Femtography), simonetta liuti (university of virginia), David Richards (Jefferson Lab)

The aim of this workshop is to bring together interdisciplinary experts to assess the current status of the 3D internal structure of the nucleon, and to identify the requirements and to develop a coherent approach to the extraction of the salient physics quantities. The workshop will include plenary talks, with dedicated time for working group discussions.
