The present review gives a survey of recent developments and applications of the Nambu-
Jona-Lasinio model with Nf= 2 and Nf= 3 quark flavors for the structure of baryons. The …

Nontopological soliton models have been successfully used to incorporate the quark
structure of hadrons into nuclear physics. These are phenomenological field theories which …

We present arguments that QCD at low momenta is reduced to a simple theory given by a
path integral over pion fields and quarks which obtain dynamical mass owing to chiral …

The electromagnetic properties of the SU (3)-flavor baryon decuplet are examined within a
lattice simulation of quenched QCD. Electric charge radii, magnetic moments, and magnetic …

We investigate theoretical uncertainties and model dependence in the extraction of the
nucleon-Δ (1232) electromagnetic transition amplitudes from the multipole data base. Our …

A reasonable low-energy chiral Lagrangian of vectors and pseudoscalars involves three a
priori unknown coefficients for terms proportional to the Levi-Civita symbol ε μ ν α β. We …

The electromagnetic transition moments of the SU (3)-flavor baryon octet to decuplet are
examined within a lattice simulation of quenched QCD. The magnetic transition moment for …

We compute the leading contributions to the magnetic dipole and electric quadrupole
moments of the baryon decuplet in chiral perturbation theory. The measured value for the …

We calculate the multipole ratios E 1+ M 1+(electric quadrupole to magnetic dipole) and S
1+ M 1+(scalar quadrupole to magnetic dipole) for the reaction γ v N→ Δ. We use the …

This revised and extended edition of the book Fields, Symmetries, and Quarks, originally
published by McGraw-Hill Book Company, Hamburg, 1989, contains a new chapter on …
