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” …

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 …

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 …

We review the spectrum and electromagnetic properties of baryons described as relativistic
three-quark bound states within QCD. The composite nature of baryons results in a rich …

We summarize the scientific opportunities for utilization of the upgraded 12GeV Continuous
Electron Beam Accelerator Facility (CEBAF) and associated experimental equipment at …

About 120 baryons and baryon resonances are known, from the abundant nucleon with u
and d light-quark constituents up to the Ξ b−=(bsd), which contains one quark of each …

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 …

The composite nature of baryons manifests itself in the existence of a rich spectrum of
excited states, in particular in the important mass region 1–2 GeV for the light-flavoured …

The vast majority of hadrons observed in nature are not stable under the strong interaction;
rather they are resonances whose existence is deduced from enhancements in the energy …

We review recent progress in the investigation of the electroexcitation of nucleon
resonances, both in experiment and in theory. We describe current experimental facilities …
