1/Nc Corrections in Meson-Baryon Scattering
Herry J. Kwee, Richard F. Lebed
Abstract
Corrections to meson/ground-state baryon scattering amplitudes in the 1/Nc expansion of QCD have previously been shown to be controlled by the t-channel difference |It - Jt| of isospin and angular momentum and by the change of hypercharge Yt. Here we derive the corresponding expressions in the original scattering s channel, allowing for nonzero meson spin and nontrivial SU(3) flavor quantum numbers, and provide explicit examples of the crossing relevant for pi N --> rho N and K N scattering.
