# Chiral Symmetry of Baryons

@article{Jido2001ChiralSO, title={Chiral Symmetry of Baryons}, author={Daisuke Jido and Makoto Oka and Atsushi Hosaka}, journal={Progress of Theoretical Physics}, year={2001}, volume={106}, pages={873-908} }

We study chiral symmetry aspects of the positive and negative parity baryons by identifying them with linear representations of the chiral group SU (N f ) ⊗ SU (N f ). It is shown that there are two distinct schemes: those possessing naive and mirror assignments. We construct linear sigma models for baryons in the two assignments and examine their physical implications. Then we investigate properties of the naive and mirror nucleons microscopically by using QCD interpolating fields. Finally, we…

The chirally symmetric baryon parity-doublet model can be used as an effective description of the baryon-like objects in the chirally symmetric phase of QCD. Recently it has been found that above the…

Probing Chiral Symmetry of Nucleons by Threshold ηπ Production

- Physics

Double meson production of eta and pi mesons in the threshold region is investigated in order to determine chiral properties of the nucleon. The eta can be used as a probe for the negative parity…

Three-flavor chiral effective model with four baryonic multiplets within the mirror assignment

- Physics

We study three-flavor octet baryons by using the so-called extended Linear Sigma Model (eLSM). Within a quark-diquark picture, the requirement of a mirror assignment naturally leads to the…

Casimir effect for nucleon parity doublets
