Solitonic Baryons in a Chiral Quark Meson
نویسنده
چکیده
We consider a simple SU(2) quark soliton model based on chiral invariant quark-meson couplings. We nd axially symmetric, classically stable soliton solutions with B=2,3 and 4 (where B is the baryon number). The energy distributions corresponding to these solutions are toroidal in nature. The symmetries of the B=2 solution indicate that the ground state of this solution has the quantum numbers of the deuteron.

Heavy quark solitons.
We investigate the heavy baryons which arise as solitonic excitations in a “heavy meson” chiral Lagrangian which includes the light vector particles. It is found that the effect of the light vectors may be substantial. We also present a simple derivation which clearly shows the connection to the CallanKlebanov approach.
متن کاملVanishing of non-Abelian Berry phases in heavy solitonic baryons.
In this article, we show – using a reasoning applicable to both the excitation spectrum in the chiral bag model and the hyperfine structure of diatomic molecules – that the generic form of a nonabelian Berry potential appears in heavy quark effective theory (HQET) and that the Berry potential vanishes for the solitonheavy meson bound state in the heavy-quark limit. The vanishing of the Berry po...
متن کاملBaryons in Effective Chiral Quark Models with Polarized Dirac Sea
In this paper concepts and numerical calculations are reviewed in which baryons are considered as many body systems composed of three quarks coupled to a polarized Dirac sea. The interaction is the one of the Nambu–Jona-Lasinio model and of local and biquadratic form in a way which allows for spontaneous chiral symmetry breaking. The models are treated explicitely in the 0-boson and 1-quark loo...
متن کاملPath-integral Approach in a Chiral Quark-diquark Model to the Nucleon Structure and Interactions
We study the structure of the nuclear force by using a path-integral hadronization approach in a chiral quark-diquark model. After the construction of the chiral quark-diquark model, we hadronize it to obtain a meson-baryon Lagrangian. The effective meson-baryon Lagrangian incorporates chiral symmetry and the composite description of the mesons and baryons. Using the effective meson-baryon Lagr...
متن کاملHeavy quark solitons in the Nambu-Jona-Lasinio model.
The Nambu–Jona-Lasinio model (NJL) is extended to incorporate heavy quark spinsymmetry. In this model baryons containing one heavy quark are analyzed as bound-states of light baryons, represented as chiral solitons, and mesons containing one heavy quark. From related studies in Skyrme type models, the ground-state heavy baryon is known to arise for the heavy meson in a P–wave configuration. In ...
