1/N Corrections to the Baryon Axial Currents in QCD
Roger Dashen, Aneesh V. Manohar
Abstract
We prove that the 1/N corrections to the baryon axial current matrix elements are proportional to their lowest order values. This implies that the first correction to axial current coupling constant ratios vanishes, and that the SU(2Nf) spin-flavor symmetry relations are only violated at second order in 1/N.
