Static properties of chiral models with SU(3) group structure

Abstract

We investigate the strangeness in the framework of chiral models, such as the Skyrmion, MIT bag, chiral bag and superqualiton models, with SU(3) flavor group structure. We review the recent progresses in both the theoretical paradigm and experimental verification for strange hadron physics, and in particular the SAMPLE experiment results on the proton strange form factor. We study the color flavor locking phase in the color superconducting quark matter at high density, which might exist in the core of neutron stars, in the soliton-like superqualiton description. We explain the difficulties encountered in the application of the standard Dirac quantization to the Skyrmion and superqualiton models and treat the geometrical constraints of these soliton models properly to yield the relevant mass spectrum including the Weyl ordering corrections and the BRST symmetry structures.
