Stringent physical constraints relate the J/{psi} produced at a given transverse momentum p{sub T} to the Bjorken-x of the initial gluons. We present a new approach which takes them into account in order to explicitly investigate the p{sub T}-dependence of the shadowing effect on the J/{psi} production. Using the J/{psi} rapidity and p{sub T} spectra extracted from {radical}(s) = 200 GeV p+p data from PHENIX, we build a Glauber Monte-Carlo code which includes shadowing in two alternative ways: multiple scattering corrections or Q{sup 2} evolution of parton densities. We present our results in d+Au collisions at the same energy, notably providing the first prediction of the J/{psi} nuclear modification factor as a function of p{sub T}, and compare them to the available data by adding some nuclear absorption effect.
