    "abstract": "We study the production of cc~ pairs in nuclear reactions at SPS energies\nwithin the covariant transport approach HSD. The production of cc~ is treated\nperturbatively employing experimental cross sections while the interactions of\ncc~ pairs with baryons are included by conventional cascade-type two-body\ncollisions. Adopting 6 mb for the cc~-baryon cross sections the data on J/\\Psi\nsuppression in p+A reactions are reproduced in line with calculations based on\nthe Glauber model. Additionally the dissociation of the cc~ pairs by strings is\nincluded in a purely geometrical way. We find good agreement with experimental\ndata from the NA38 and NA50 collaboration with an estimate for the string\nradius of ~0.2-0.3 fm.",
