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” …

There are two mass generating mechanisms in the standard model of particle physics (SM).
One is related to the Higgs boson and fairly well understood. The other is embedded in …

The last decade has seen a marked shift in how the internal structure of hadrons is
understood. Modern experimental facilities, new theoretical techniques for the continuum …

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 …

Understanding the origin and dynamics of hadron structure and in turn that of atomic nuclei
is a central goal of nuclear physics. This challenge entails the questions of how does the …

Visible matter is characterised by a single mass scale; namely, the proton mass. The
proton's existence and structure are supposed to be described by 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 …

We reconstruct ghost and gluon spectral functions in 2+ 1 flavor QCD with Gaussian process
regression. This framework allows us to largely suppress spurious oscillations and other …

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 …
