We show that the RHIC data on $J/ψ$ production in d-Au collisions can be described with nuclear shadowing alone (sigma_{abs} = 0). The corresponding results for Au-Au collisions are also presented and compared with available data.17 pages, 2 figures, published versionHigh Energy Physics - Phenomenologytext
