Abstract
In view of important implications in the B decay, the 0-0- decay modes of J/psi are analyzed with broken flavor SU(3) symmetry in search for long-distance final-state interactions. If we impose one mild theoretical constraint on the electromagnetic form factors, we find that a large phase difference of final-state interactions is strongly favored between the one-photon and the gluon decay amplitudes. Measurement of the \pi+\pi- and K+K- cross sections off the J/psi peak in e+e- annihilation can settle the issue without recourse to theory.
