Abstract
We calculate the nuclear suppression for and production within a coupled channel approach in the subspace of the and states. We are able to explain why (i) and show the same suppression from 200 to 800 GeV in proton-nucleus collisions and why (ii) is absorbed more strongly than in nucleus-nucleus collisions at 200 GeV. Our numerical result, which includes only interactions with nucleons, accounts for half of the observed suppression in sulfur uranium collisions.
