TL;DR: In this paper, the current status of experimental and theoretical understanding of the axial nucleon structure at low and moderate energies is reviewed, including (quasi)elastic (anti)neutrino-nucleon scattering, charged pion electroproduction off nucleons and ordinary as well as radiative muon capture on the proton.

TL;DR: In this article, the mixing of quarks of one flavor into the wave function of constituent quarks from a different flavor when chiral symmetry breaks dynamically in the Nambu-Jona-Lasinio model was studied.

TL;DR: In this article, a generalized Nambu-Jona-Lasinio lagrangian including scalar, pseudoscalar, vector and axial-vector mesons was constructed.

TL;DR: The behavior of the Nambu-Jona-Lasinio model at high density is discussed in this paper, where it is shown that the decrease of the meson mass with increasing density suggests a softening of the equation of state at high densities in most relativistic mean field calculations.

TL;DR: The Nambu--Jona-Lasinio model at finite temperature and density is used to investigate the static and dynamical properties of the pion and near the chiral phase transition the pions decouple from matter.
