Abstract: (APS)
Quasielastic meson-baryon scattering is reformulated in t-channel language (meson exchange) instead of s-channel language (baryon-resonance formation), by use of skyrmion methods. A new selection rule emerges, valid to leading order in large Nc. The isospin of the exchanged state must equal its total angular momentum (spin+orbital). Differences between the two-flavor and the three-flavor approach are discussed.- MESON BARYON: INTERACTION
