In the framework of quantum chromodynamics (QCD), parton distribution functions (PDFs)
quantify how the momentum and spin of a hadron are divided among its quark and gluon …

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 …

A bstract We show how several properties of the QCD axion can be extracted at high
precision using only first principle QCD computations. By combining NLO results obtained in …

We perform the first global QCD analysis of polarized inclusive and semi-inclusive deep-
inelastic scattering and single-inclusive e+ e-annihilation data, simultaneously fitting the …

We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

The current status of electric dipole moments of diamagnetic atoms which involves the
synergy between atomic experiments and three different theoretical areas, ie particle …

We determine the axial, scalar and tensor isovector charges of the nucleon, sigma and
cascade baryons as well as the difference between the up and down quark masses, mu-md …

We determine within lattice QCD the nucleon spin carried by valence and sea quarks and
gluons. The calculation is performed using an ensemble of gauge configurations with two …

A bstract We provide expressions for the nonperturbative matching of the effective field
theory describing dark matter interactions with quarks and gluons to the effective theory of …

A bstract The QCD axion is one of the most compelling solutions of the strong CP problem.
There are major current efforts into searching for an ultralight, invisible axion, which is …
