This report describes the physics case, the resulting detector requirements, and the evolving
detector concepts for the experimental program at the Electron-Ion Collider (EIC). The EIC …

Abstract This White Paper aims at highlighting the important benefits in the science reach of
the EIC. High luminosity operation is generally desirable, as it enables producing and …

The physics of the gravitational form factors of the proton, as well as their understanding
within quantum chromodynamics, has advanced significantly in the past two decades …

Abstract This White Paper presents an overview of the current status and future perspective
of QCD research, based on the community inputs and scientific conclusions from the 2022 …

The physics related to the form factors of the energy–momentum tensor spans a wide
spectrum of problems, and includes gravitational physics, hard-exclusive reactions, hadronic …

The proton, one of the components of atomic nuclei, is composed of fundamental particles
called quarks and gluons. Gluons are the carriers of the force that binds quarks together …

This article reviews our present understanding of QCD spin physics: the proton spin puzzle
and new developments aimed at understanding the transverse structure of the nucleon …

Prospects for quarkonium-production studies accessible during the upcoming high-
luminosity phases of the CERN Large Hadron Collider operation after 2021 are reviewed …

We review the phenomenological framework for accessing Generalized Parton Distributions
(GPDs) using measurements of Deeply Virtual Compton Scattering (DVCS) from a proton …

The gravitational form factors (GFFs) of hadrons encode the matrix elements of the energy-
momentum tensor of QCD. These quantities describe how energy, spin, and various …
