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).

Important Workshop Details

  • Please complete the workshop registration AND the form needed for a gate pass/site access [see REGISTRATION & SITE ACCESS page].
  • Workshop reception will be Monday evening [location: 2nd floor lobby, Bldg 241].
  • Workshop dinner will be Wednesday evening [location: Topaz].
  • An excursion to downtown Chicago is planned for Thursday afternoon.
  • We plan to end the workshop before 1pm on Friday.


We would like to gently encourage all participants to consider becoming a member of the APS Topical Group on Hadronic Physics (GHP). The GHP provides an important vehicle to promote our science to the broader physics community, funding agencies, and the general public. An increase in GHP membership will lead to more talks at APS meetings and the ability to nominate more APS fellows. If you have any questions please contact a member of the GHP Executive Committee. Further details are given in a slide found here.

QCD Evolution 2019

The QCD Evolution Workshop explores developments in theory and experiment related to evolution and factorization in TMDs, GPDs, and related areas.

Celebrating more than 70 years of discovery at Argonne National Laboratory

This project is supported by the JSA Initiatives Fund Program, a commitment from the JSA owners, SURA and PAE Applied Technologies. Initiatives Funds support programs, initiatives, and activities that further the scientific outreach, promote the science, education and technology of the Jefferson Lab and benefit the Lab's extended user community in ways that complement the Lab’s basic and applied research missions.
