Introduction and Objectives

The QCD Evolution workshop series started in 2011 with a two-day meeting held at Jefferson Lab that addressed the theoretical underpinnings of generalized parton distributions (GPDs) and transverse momentum distributions (TMDs), with a particular focus on the QCD evolution of the non-collinear TMDs. Since this initial meeting QCD Evolution has grown to be a leading hadron physics meeting with a focus on hadron tomography.

A main objective of QCD Evolution is to provide a forum to discuss the recent scientific accomplishments in areas such as Transverse Momentum Distributions (TMDs), Generalized Parton Distributions (GPDs), and small-x physics, together wth advances in perturbative and non-perturbative techniques within Quantum Chromodynamics (QCD). In doing so this workshop also aims to support and guide the physics programs at facilities such as Jefferson Lab, the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab, Fermi National Accelerator Laboratory, and the Large Hadron Collider (LHC) complex at CERN. The workshop is also central to the planning for the next-generation nuclear physics facility in the US, the Electron Ion Collider (EIC).
