In the framework of the Glauber-Gribov field theory in the eikonal approximation, we show that in hadron-nucleus collisions in the high-energy limit and under specific conditions, the rescattering contributions to the J/\ensuremathψ production cross section vanish, leading to an A1 dependence on the atomic number A-except for nuclear effects in the nucleus structure function, the so-called shadowing. We show that the data from the BNL Relativistic Heavy Ion Collider on J/\ensuremathψ production in d-Au collisions can be described with nuclear shadowing alone (\ensuremathσabs=0). The corresponding results for Au\text\ensuremath-Au collisions are also presented and compared with available data.
