Abstract: The ��-> (��, ��)P^-��decays, where P^-=��^-, K^-, are considered within a phenomenological model with dominance of meson intermediate states. We assume SU(3) flavor symmetry to fix some of the unknown strong interaction couplings. Our predictions for the ��-> ��(��^-, K^-)��branching fractions are in good agreement with recent measurements of the BABAR and BELLE Collaborations.<br />15 pages, 3 figures
