    "abstract": "We demonstrate that the main part of the observed nuclear suppression of\ndilepton and charmonium production, especially the x-dependence of the\nsuppression, can be explained by the absorption of fast initial partons. We\nassume the absorption to be x1-dependent and determine the empirical form of\nthis dependence. Several reactions at different energies are described with the\nsame parametrization of the absorption cross section. The factorization theorem\nconstraints and some alternative models are discussed. The obtained description\nof data allows to make conclusions about the origin of nuclear effects in\nhadro- and electroproduction. In particular, it is concluded that the parton\nrecombination and the excess pion contribution are unimportant in nuclei and an\nindication of excess gluons at $x_{2}\\sim 0.1$ is observed.",
