Abstract
We study the low energy pion-hyperon interaction considering effective nonl inear chiral invariant Lagrangians including pions, rho mesons, sigma meson s, hyperons, and corresponding resonances. Then we calculate the S- and P-w ave phase shifts, total cross sections, angular distributions, and polariza tions for the momentum in the center-of-mass frame up to k = 400 MeV. With these results we discuss the CP violation in the Xi --> Lambda pi and Omega --> Xi pi weak decays.
