| Abstract | The symmetry breaking corrections to the pion–baryon couplings vanish to first order in 1/Nc, where Nc is the number of colours. Loop graphs with octet and decuplet intermediate states cancel to various orders in Nc as a consequence of the large-Nc spin-flavour symmetry of QCD baryons. The baryon axial vector current is computed at one-loop order in heavy baryon chiral perturbation theory in the large Nc limit. 1/Nc corrections in the case of gA in QCD are presented here. |
