    • Abstract

       

      Weak decay modes (1/2+ → 3/2+ + 0/γ) of charmed baryons are studied. Relations among the various decay amplitudes are derived in isospin, SU(3), SU(4) and SU(8)w symmetries. Sextet dominance in SU(3) forbidsB(3) →D(10) +P(3*) decays. 20″ dominance in SU(4) specifies all the decays in terms of Θ decays. Weak decays of Θ*3++ and Θ are also discussed. SU(8)w symmetry predictsα$$(\Omega \bar k) = 0$$, which is consistent with the experimental value.
