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 …

1 Executive summary The purpose of this document is to outline the developing scientific
case for pursuing an energy upgrade to 22 GeV of the Continuous Electron Beam …

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 …

Yang–Mills theories are an important building block of the standard model and in particular
of quantum chromodynamics. Its correlation functions describe the behavior of its …

The Lagrangian that defines quantum chromodynamics (QCD), the strong interaction piece
of the Standard Model, appears very simple. Nevertheless, it is responsible for an …

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 …

Correlation functions of Yang-Mills theory in the Landau gauge are calculated from their
equations of motion. The employed setup is completely parameter free and leads, within …

In Quantum Chromodynamics, the Schwinger mechanism endows the gluons with an
effective mass through the dynamical formation of massless bound-state poles that are …
