The QCD Evolution Workshop 2021 will be conducted online via ZOOM platform, hosted by the University of California Los Angeles (UCLA), during May 10 - 14, 2021. Only registered participants will recive the links to join the conference.
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.
The main objective of QCD Evolution Workshop 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 with advances in perturbative and non-perturbative techniques within Quantum Chromodynamics (QCD), such as lattice QCD and effective field theory techniques.
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).
To register for the workshop, and submit an abstract if you plan to give a talk, please refer to the registration page.
