These couplings are a crucial ingredient in the calculation of cross sections for the processes pi J/psi -> D(*)Dbar(*), an important background for the J/psi suppression signal in quark-gluon plasma.7 pages, LaTeX, 4 figures, in Workshop on Hard Probes in Heavy Ion Collisions at the LHCHigh Energy Physics - PhenomenologyNuclear Theorytext
