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 …

Precise proton and neutron form factor measurements at Jefferson Lab, using spin
observables, have recently made a significant contribution to the unraveling of the internal …

Classical nuclear theory deals with a many-body system of neutrons and protons interacting
nonrelativistically through two-body potentials. It has, of course, long been realized that …

A previously derived model in which a baryon is treated as a three-quark bag that is
surrounded by a cloud of pions is used to compute the static properties of the nucleon. The …

By incorporating chiral invariance in the MIT bag model, we are led to a theory in which the
pion field is coupled to the confined quarks only at the bag surface. An equivalent quantized …

Several phenomenological models of hadrons are derived from quantum chromodynamics
(QCD). Functional-integral methods are used to obtain an approximate bilocal-field …

The nucleon is modeled, using light front dynamics, as a relativistic system of three bound
constituent quarks surrounded by a cloud of pions. The pionic cloud is important for …

The soliton bag model of Friedberg and Lee is investigated. We study in detail the numerical
solution of the mean-field limit of the model and develop quantum corrections to this …

The author discusses the application of the quark cluster model to the baryon-baryon
interaction. The short-range repulsion and spin-orbit force in the nucleon-nucleon potential …

The interaction of mesons is modelled as nonrelativistic pointlike particles interacting via
effective potentials. The effective potentials are obtained by equating the Born order T-matrix …
