Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

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 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 …

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 …

We give an overview of the theory for generalized parton distributions. Topics covered are
their general properties and physical interpretation, the possibility to explore the three …

The generalized parton distributions, introduced nearly a decade ago, have emerged as a
universal tool to describe hadrons in terms of quark and gluonic degrees of freedom. They …

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

We argue that generalized parton distributions (GPDs), accessible in hard exclusive
processes, carry information about the spatial distribution of forces experienced by quarks …

We compute the cross section for leptoproduction of the real photon off the nucleon, which is
sensitive to the deeply virtual Compton scattering amplitude with power accuracy. Our …

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