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

Proton-proton collisions at the LHC generate a high-intensity collimated beam of neutrinos
in the forward (beam) direction, characterised by energies of up to several TeV. The recent …

We perform the first simultaneous extraction of unpolarized parton distributions and
fragmentation functions from a Monte Carlo analysis of inclusive and semi-inclusive deep …

We present results on the quark unpolarized, helicity and transversity parton distributions
functions of the nucleon. We use the quasiparton distribution approach within the lattice …

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 …

The QCD effective charge α g 1 (Q) is an observable that characterizes the magnitude of the
strong interaction. At high momentum Q, it coincides with the QCD running coupling α s (Q) …

We present the first lattice QCD calculation of the charm quark contribution to the nucleon
electromagnetic form factors GE, M c (Q 2) in the momentum transfer range 0≤ Q 2≤ 1.4 Ge …

The holographic light-front QCD framework provides a unified nonperturbative description of
the hadron mass spectrum, form factors and quark distributions. In this article we extend …

We use analytic continuation to extend the gauge-gravity duality nonperturbative description
of the strong force coupling into the transition, near-perturbative, regime where perturbative …
