Renormalization of the baryon axial vector current in large-N_c chiral perturbation theory

摘要

The baryon axial vector current is considered within the combined framework of large-N_c baryon chiral perturbation theory (where N_c is the number of colors) and the baryon axial vector couplings are extracted. Loop graphs with octet and decuplet intermediate states are systematically incorporated into the analysis.
