1 Executive summary The purpose of this document is to outline the develo** 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 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 …

Understanding the strong interaction dynamics that govern the emergence of hadron mass
(EHM) represents a challenging open problem in the Standard Model. In this paper we …

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

Recent experimental and theoretical advancements have led to significant progress in our
understanding of the electromagnetic structure of nucleons (N), nucleon excitations (N∗) …

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 …

Modern and anticipated facilities will deliver data that promises to reveal the innermost
workings of quantum chromodynamics (QCD). In order to fulfill that promise …

We use a continuum quark+ diquark approach to the nucleon bound-state problem in
relativistic quantum field theory to deliver parameter-free predictions for the nucleon axial …

Advances in the exploration of the spectrum and structure of the excited states of the
nucleon from experiments with electromagnetic probes on proton targets are presented …
