Vector meson pole dominance in J/psi decays into mesons

The validity of the assumption that J/psi decays into mesons proceed via ω, phi and rho0 poles followed by cascade decays is examined. GAMMA(J/psi→Bπ) is well reproduced by using GAMMA(J/psi→rhoπ), GAMMA(ω→rhoπ), GAMMA(B→ωπ) and the B→ωπ helicity structure. The structure of OZI-violating J/psi-V0 transitions including the electromagnetic contribution is examined, and compared with the data on inclusive J/psi decay. (Auth.)
