Abstract
The approach to problem of nuclear shadowing based on Gribov Reggeon calculus is presented. Here the total cross section of hA interaction is found in a parameter-free description, employing the new data on the gluon density of the Pomeron, measured with high precision at HERA, as input. The model is then applied for calculation of J/ψ production in dAu collisions at top RHIC energy. It is shown that the theoretical estimates are in a very good agreement with the PHENIX data, and further predictions for the J/ψ suppression in pPb collisions at energies of LHC are made.
