Abstract

We investigate the antitriplet and sextet heavy baryon systems with JP=12+,32+J^P= \frac{1}{2}^+, \frac{3}{2}^+ in the framework of the heavy baryon chiral perturbation theory. We first calculate the chiral corrections to the heavy baryon mass from the SU(3) flavor breaking effect up to O(p3)O(p^3). Then we extend the same formalism to calculate the chiral corrections to the axial charges of the heavy baryons in the isospin symmetry limit.
