Phase Structure of a Quantized Chiral Soliton on S

A quantization of a breathing motion of a rotating chiral soliton on S 3 is performed in terms of a family of trial functions for a profile function of the hegdehog ansatz. We determine eigenenergies of the quantized S 3 skyrmion by solving the Schrödinger equation of the breathing mode for several lower spin and isospin states varying the Skyrme term constants e. When S 3 radius is smaller tha...

Quantized meson fields in and out of equilibrium. II: Chiral condensate and collective meson excitations

We develop a quantum kinetic theory of the chiral condensate and meson quasiparticle excitations using the O(N) linear sigma model which describe the chiral phase transition both in and out of equilibrium in a unified way. A mean field approximation is formulated in the presence of mesonic quasi-particle excitations which are described by generalized Wigner functions. It is shown that in equili...

Flavour Stability of the Chiral Vacuum and Scalar Meson Dynamics

Previous work relating the flavour variation of the chiral order parameters Fπ, 〈ūu〉 and S-wave scattering data, based on chiral sum rules and chiral perturbation theory at order p, is extended to include O(p) corrections. The finding of a significant decrease of these order parameters, particularly 〈ūu〉, with the number of flavours increasing from NF = 2 to NF = 3 is confirmed, modulo an assum...

Self-Consistent Pushing and Cranking Corrections to the Meson Fields of the Chiral Quark-Loop Soliton

We study translational and spin-isospin symmetry restoration for the two-flavor chiral quark-loop soliton. Instead of a static soliton at rest we consider a boosted and rotating hedgehog soliton. Corrected classical meson fields are obtained by minimizing a corrected energy functional which has been derived by semi-classical methods (’variation after projection’). We evaluate corrected meson fi...

Nucleon described by the chiral soliton in the chiral quark soliton model

We give a survey of recent development and applications of the chiral quark soliton model (also called the Nambu–Jona-Lasinio soliton model) with Nf=2 and Nf=3 quark flavors for the structure of baryons. The model is an effective chiral quark model obtained from the instanton liquid model of the quantum chromodynamics. Mesons appear as quark-antiquark excitations and baryons arise as non-topolo...
