Abstract：
Using the branching fractions of J/ψ to baryon-antibaryon decays, listed in PDG2004, we analyze the SU(3) flavor symmetry of the baryon octets and study the interference effects between the electromagnetic and strong interactions. The effects of SU(3) breaking are obtained by fitting the branching fractions of J/ψ→BB.
