Axial vector coupling constant of the constituent quark

Journal Article · · Bulletin of the American Physical Society
OSTI ID:387158

We analyze the axial vector coupling of a constituent quark in the large-N{sub c} limit. We point out that the {pi} - A{sub 1} mixing mechanism produces a contribution to 1 - 9{sub A} at the level N{sup 0}{sub c}. Following Weinberg, we use the Adler-Weisberger sum rule and demonstrate that the reggeized p-meson exchange in the t-channel generates the leading N{sub e}-contribution to g{sub A}.
