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 …

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

The dynamics of the QCD gauge sector give rise to non-perturbative phenomena that are
crucial for the internal consistency of the theory; most notably, they account for the …

Beginning with results for the leading-twist two-particle distribution amplitudes of π π-and K-
mesons, each of which exhibits dilation driven by the mechanism responsible for the …

The last five years have brought considerable progress in the study of the bound-state
problem in continuum quantum field theory. We highlight a subset of that progress; viz., that …

The theory of the strong interaction, quantum chromodynamics (QCD), describes the
generation of hadronic masses and the state of hadronic matter during the early stages of …

In 1967, Faddeev and Popov were able to quantize the Yang–Mills theory by introducing
new particles called ghost through the introduction of a gauge. Ever since, this quantization …

Abstract Emergent Hadron Mass (EHM) is a mechanism capable of explaining both the
unnaturally small (pion) and large (proton) masses of hadrons and if not the origin of …

Using lattice configurations for quantum​​​​​ chromodynamics (QCD) generated with
three domain-wall fermions at a physical pion mass, we obtain a parameter-free prediction …

Within contemporary hadron physics there are two common methods for determining the
momentum-dependence of the interaction between quarks: the top-down approach, which …
