Description

The aim of the workshop is to provide an overview of the current status of the experimental and theoretical studies, including lattice QCD, of exclusive reactions and to discuss future possible exclusive measurements as well as needed theoretical studies. In particular, we will focus on the study of hard exclusive meson production and a sample of Compton-like processes, other than DVCS, in lepton-hadron and hadron-hadron collisions, to access generalised parton distributions and the mass and pressure distribution of hadrons. We will also discuss the study of double Drell-Yan, dihadron and dijet production, which is sensitive to Wigner distributions. Unless conditions prevent it, the workshop is foreseen to be attended in person at the University of Virginia Tech in Blacksburg, VA, USA.

Thank you to all the participants
