Abstract
We extend the 1/N{sub c} expansion meson-baryon scattering formalism to cases in which the final state contains more than two particles. We first show that the leading-order large N{sub c} processes proceed through resonant intermediate states (e.g., {rho}N or {pi}{delta}). We then tabulate linear amplitude expressions for relevant processes and find that the pole structure of baryon resonances can be uniquely identified by their (non)appearance in {eta}N or mixed partial-wave {pi}{delta} final states. We also show that quantitative predictions of {pi}N to {pi}{delta} branching ratios predicted at leading order alone do not agree with measurements, but the inclusion of 1/N{sub c} corrections is ample to explain the discrepancies.
