N2 - Extending earlier work on strong-coupling meson-baryon scattering in QCD2, we derive the effective meson-baryon action for any value of the coupling constant, in the large-Nc limit. Colour degrees of freedom play an important role, and we show that meson-baryon scattering can be formulated as a relativistic potential problem. We distinguish two cases that are non-trivial for unequal quark masses, and present the resulting equations for meson-baryon scattering amplitudes.
