Dyson-Schwinger equations: Density, temperature and continuum strong QCD
TL;DR: In this article, the authors provide a practitioners' guide to features of the Dyson-Schwinger equations and canvasses phenomenological applications to light meson and baryon properties in cold, sparse QCD.

Mass spectra and Regge trajectories of light mesons in the relativistic quark model
TL;DR: The relativistic treatment of the light quark dynamics results in mass spectra which agree well with available experimental data for the masses of the most well-established states as discussed by the authors.

Extended NJL model for light and heavy mesons without q-q thresholds
TL;DR: In this paper, the authors considered the NNL model as an effective quark theory to describe the interaction which is responsible for the quark flavor dynamics at intermediate energies and proposed an infrared cut-off which dropped off the unknown confinement part of quark interaction, which is believed to be less important for the flavor dynamics.

On gauge invariance and vacuum polarization
TL;DR: In this paper, it was shown that the extraction of gauge invariants from a formally gauge invariant theory is ensured if one employs methods of solution that involve only gauge covariant quantities.

Dynamical Model of Elementary Particles Based on an Analogy with Superconductivity. II
Yoichiro Nambu,G. Jona-Lasinio +1 more
TL;DR: In this paper, a superconductive solution describing the proton-neutron doublet is obtained from a nonlinear spinor field Lagrangian, and the pions of finite mass are found as nucleon-antinucleon bound states by introducing a small bare mass into the Lagrangians which otherwise possesses a certain type of the ∆-ensuremath{gamma{5}$ invariance.

Chiral perturbation theory to one loop
J. Gasser,Heinrich Leutwyler +1 more
TL;DR: In this article, the low energy representation of several Green's functions and form factors and of the na scattering amplitude are calculated in terms of a few constants, which may be identified with the coupling constants of a unique effective low energy Lagrangian.

Axial vector vertex in spinor electrodynamics
TL;DR: In this article, the axial-vector vertex in spinor electrodynamics has anomalous properties which differ with those found by the formal manipulation of field equations, and the divergence of axial vector current is not the usual expression calculated from the field equations.

Chiral Perturbation Theory: Expansions in the Mass of the Strange Quark
Jürg Gasser,Heinrich Leutwyler +1 more
TL;DR: In this paper, the authors construct the generating functional of U(3)×U(3), which allows them to calculate the Green functions up to and including terms of order p4 (at fixed radio m quark p 2 ) in terms of a few coupling constants which chiral symmetry leaves undetermined.
