Meson-baryon scattering
= Meson-baryon scattering
Scattering with one <meson> and one <baryon> in the initial and final states. The <strong interaction> conserves <electric charge>, <baryon number>, net <strangeness>, four-momentum, total <angular momentum>, and parity. Approximate <isospin> symmetry imposes additional relations among charge-channel amplitudes.
