J/psi absorption by nucleons in the meson-exchange model Academic Article uri icon


  • We reinvestigate the J/ dissociation processes induced by the reactions with nucleons, J/+ND(*)+c, in the meson-exchange model. Main constraints used in this work are vector-meson dominance and charm vector-current conservation. We show that the cross section for J/+ND+c can be larger than that for J/+ND*+c when these constraints are imposed. The dependence of the cross sections on the coupling constants is analyzed in detail, and the comparison with the recent quark-interchange model predictions is also made. 2007 The American Physical Society.
