Baryon polarization in low-energy unpolarized meson-baryon scattering

Abstract

We compute the polarization of the final-state baryon, in its rest frame, in low-energy meson--baryon scattering with unpolarized initial state, in Unitarized BChPT. Free parameters are determined by fitting total and differential cross-section data (and spin-asymmetry or polarization data if available) for $p{K}^{-}$, $p{K}^{+}$ and $p{\pi }^{+}$ scattering. We also compare our results with those of leading-order BChPT.
