In this note we present an evaluation of the couplings JD(*)D(*) and JD(*)D(*)pi in the Constituent Quark Model. These couplings are a crucial ingredient in the calculation of cross sections for the processes pi J/psi -> D(*)Dbar(*), an…
We examine angular distributions of leptons arising from the decay of J/psi in inclusive hadroproduction. Taking into account feed-down contributions from chi_{1,2}, a flat distribution emerges without fine tuning parameters. Changes in the…

The observed features of $\psi'$ to $J/\psi$ suppression in $pA$ and nucleus-nucleus collisions can be explained in terms of a two-component absorption model. For the hard component of the absorption due to the interaction of the produced…
