Abstract
Chiral symmetry of baryons is studied by identifying them with linear representations of the chiral symmetry group. We show that two distinctive chiral assignments are possible. Based on these two assignments, linear sigma models are constructed and their physical implications are studied. Then we propose experiments to observe the relative sign of axial charges of the positive and negative parity nucleons through the π and η productions at the threshold region. This can be used as a probe to distinguish the two chiral assignments.
