Axial Properties of Baryon Ground and Resonant States

We report results from a study of axial charges of baryon ground and resonant states with relativistic constituent quark models. In particular, we consider the axial charges of the octet and decuplet baryons N , Σ, Ξ, Δ, Σ*, and Ξ*. The theoretical predictions are compared to experiment, in the case...

Zusammenfassung:	We report results from a study of axial charges of baryon ground and resonant states with relativistic constituent quark models. In particular, we consider the axial charges of the octet and decuplet baryons N , Σ, Ξ, Δ, Σ, and Ξ. The theoretical predictions are compared to experiment, in the case of the N , and to results from other approaches, especially from lattice quantum chromodynamics and chiral perturbation theory. Some remarks are also made regarding the role of axial charges for spontaneous breaking of chiral symmetry.
