Abstract 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 made within the context of Dyson–Schwinger equation analyses of cold, sparse hadrons. Our focus is primarily on advances in the reliable computation, explanation and prediction of quantities that are truly measurable; but we also review aspects of a new paradigm that has condensates contained within hadrons, and explain that the asymptotic form of parton distribution amplitudes and functions are practically unreachable with terrestrial facilities. Given the pace of expansion in experiment and improvement in theory, it appears possible that the next five years will bring profound growth in our store of knowledge about hadrons and nuclei.

Nucleon-nucleon correlations, short-lived excitations, and the quarks within (2016, background): “ucleon wave function, so that the eects of the medium on the relevant components can be correctly included. Lattice calculations, .e.g (Ji, 2013; Lin et al., 2015), and the Dyson-Schwinger approach (Cloet and Roberts, 2014) are making progress on computing free nucleon parton distributions. It also ”
Baryons as relativistic three-quark bound states (2016, methodology): “The photon vertices are constructed from their Ward-Takahashi identities, together with transverse parts either based on ρ-meson pole ansätze or implementing a quark anomalous magnetic moment [505].”
The QCD running coupling (2016, methodology): “Additionally, it has been shown using the Schwinger–Dyson equations for the quark propagator that if one assumes a Gaussian form for the QCD running coupling, the quark propagator has poles above and below the real axis, consistent with quark confinement [207].”
QCD at finite temperature and chemical potential from Dyson–Schwinger equations (2018, background): “are available [268, 303, 304, 370, 371].”
