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” …

We discuss our present knowledge of α s, the fundamental running coupling or effective
charge of Quantum Chromodynamics (QCD). A precise understanding of the running of α s …

Abstract The Large Hadron–Electron Collider (LHeC) is designed to move the field of deep
inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting …

We review the present theoretical and empirical knowledge for α s, the fundamental
coupling underlying the interactions of quarks and gluons in Quantum Chromodynamics …

In this report we explore the remarkable connections between light-front dynamics, its
holographic mapping to gravity in a higher-dimensional anti-de Sitter (AdS) space, and …

We review the spectrum and electromagnetic properties of baryons described as relativistic
three-quark bound states within QCD. The composite nature of baryons results in a rich …

The structure of generalized parton distributions is determined from light-front holographic
QCD up to a universal reparametrization function w (x) which incorporates Regge behavior …

The topical workshop Strong QCD from Hadron Structure Experiments took place at
Jefferson Lab from November 6–9, 2019. Impressive progress in relating hadron structure …

We review the present understanding of the spin structure of protons and neutrons, the
fundamental building blocks of nuclei collectively known as nucleons. The field of nucleon …

High-precision nucleon-resonance electroproduction data on a large kinematic domain of
energy and momentum transfer have proven crucial in revealing novel features of strong …
