Query: J/Psi strong couplings to the vector mesons   We present a study of the cross sections J/Psi X --> D^(*) \bar D^(*) (X =
rho, Phi) based on the calculation of the effective tri- and four-linear
couplings
  J/Psi (X) D^(*) \bar D^(*) within a constituent quark model. In particular,
the details of the calculation of the four-linear couplings J/Psi X D^(*)\bar
D^(*) are given. The results obtained have been used in a recent analysis of
J/Psi absorption by the hot hadron gas formed in peripheral heavy-ion
collisions at SPS energies.
