(Jefferson Lab) ; Heinrich, Gudrun (KIT, Karlsruhe, TP) ; Jakobs, Karl (Freiburg U.) ; Meyer, Curtis A. (Carnegie Mellon U.) ; Orginos, Kostas (Jefferson Lab ; William-Mary Coll.) ; Strickland, Michael (Kent State U.) et al.
This paper presents a comprehensive review of both the theory and experimental successes of Quantum Chromodynamics, starting with its emergence as a well defined theory in 1972-73 and following developments and results up to the present day. Topics include a review of the earliest theoretical and experimental foundations; the fundamental constants of QCD; an introductory discussion of lattice QCD, the only known method for obtaining exact predictions from QCD; methods for approximating QCD, with special focus on effective field theories; QCD under extreme conditions; measurements and predictions of meson and baryon states; a special discussion of the structure of the nucleon; techniques for study of QCD at high energy, including treatment of jets and showers; measurements at colliders; weak decays and quark mixing; and a section on the future, which discusses new experimental facilities or upgrades currently funded.

Pion and Kaon Structure at the Electron-Ion Collider
/ Aguilar, Arlene C. (Campinas State U.) ; Ahmed, Zafir (Regina U.) ; Aidala, Christine (Michigan U.) ; Ali, Salina (Catholic U.) ; Andrieux, Vincent (Illinois U., Urbana (main) ; CERN) ; Arrington, John (Argonne (main)) ; Bashir, Adnan (IFM-UMSNH, Michoacan) ; Berdnikov, Vladimir (Catholic U.) ; Binosi, Daniele (ECT, Trento ; Fond. Bruno Kessler, Trento) ; Chang, Lei (Nankai U.) et al.
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 roughly 1 GeV mass-scale that characterizes atomic nuclei appear; why does it have the observed value; and, enigmatically, why are the composite Nambu-Goldstone (NG) bosons in quantum chromodynamics (QCD) abnormally light in comparison? In this perspective, we provide an analysis of the mass budget of the pion and proton in QCD; discuss the special role of the kaon, which lies near the boundary between dominance of strong and Higgs mass-generation mechanisms; and explain the need for a coherent effort in QCD phenomenology and continuum calculations, in exa-scale computing as provided by lattice QCD, and in experiments to make progress in understanding the origins of hadron masses and the distribution of that mass within them.

Three-body scattering: Ladders and Resonances

(ECT, Trento ; INFN, Genoa ; Fond. Bruno Kessler, Trento) ; Ketzer, B. (Bonn U., HISKP) ; Szczepaniak, A.P. (Indiana U., CEEM ; Indiana U. ; Jefferson Lab)
We discuss unitarity constraints on the dynamics of a system of three interacting particles. We show how the short-range interaction that describes three-body resonances can be separated from the long-range exchange processes, in particular the one-pion-exchange process. [...]
