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 …

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

This report is based on a ten-week program on" Gluons and the quark sea at high-energies",
which took place at the Institute for Nuclear Theory in Seattle in Fall 2010. The principal aim …

This work reviews the recent developments in the field of generalized parton distributions
(GPDs) and deeply virtual Compton scattering in the valence region, which aim at extracting …

Generalized parton distributions have been introduced in recent years as a suitable
theoretical tool to study the structure of the nucleon. Unifying the concepts of parton …

We produce the light-front wave functions (LFWFs) of the nucleon from a basis light-front
approach in the leading Fock-sector representation. We solve for the mass eigenstates from …

We present the first measurement of the timelike Compton scattering process, γ p→ p′
γ*(γ*→ e+ e-), obtained with the CLAS12 detector at Jefferson Lab. The photon beam …

The beam-spin asymmetries in the hard exclusive electroproduction of photons on the
proton (e→ p→ ep γ) were measured over a wide kinematic range and with high statistical …
