Phys. Rev. Lett. 71, 1787–1790 (1993)Nc-counting rules and the axial vector coupling constant of the constituent quarkReceived 10 May 1993; published in the issue dated 20 September 1993 We analyze the axial vector coupling of the constituent quark in the large-Nc limit and point out mechanisms which yield 1-gA∼Nc0. © 1993 The American Physical Society URL:
