Abstract

We compute the spin asymmetry and polarization of the final-state baryon in its rest frame in two-body meson–baryon low-energy scattering with an unpolarized initial state to lowest non-trivial order in BChPT. The required absorptive amplitudes are obtained analytically at the one-loop level. We discuss the polarization results numerically for several meson–baryon processes. Even at low energies above threshold, where BChPT can reasonably be expected to be applicable, sizable values of polarization are found for some processes.
