✦ Synopsis

We give a survey of recent development and applications of the chirM quark soliton model (also called the Nambu-Jona-Lasinio soliton model) with Nf=2 and N/=3 quark flavors for the structure of baryons. The model is an effective chirM quark model obtained from the instanton liquid model of the quantum chromodynamics. Mesons appear as quark-antiquark excitations and baryons arise as non-topological solitons with three valence quarks and a polarized Dirac sea. In this model, a wide variety of observables of baryons is considered.

Properties of hedgehog solitons in a chiral quark model with nonlocal regulators are described. We discuss the formation of the hedgehog soliton, the quantization of the baryon number, the energetic stability, the gauging and construction of Noether currents with help of path-ordered P -exponents, a
