摘要：

Baryons B(Qqq') for heavy quarks Q = c,b,t, and light quarks q = u,d,s, are considered. Strong interaction coupling-constant sum rules with first-order breaking of SU(3) flavor symmetry are determined for reactions B -> B' + M where B = B(Qqq'), B' = B(Qqq '') and M = M(q'q '') is a light meson. Specific applications to couplings of J(P) = 1/2(+) charmed and bottom baryons are presented. Also, SU(3) Clebsch-Gordan coefficients for the product of representations 6 circle times 8 are explicitly determined.
