    "abstract": "We have evaluated the Drell-Yan cross section in nuclei paying special\nattention to the meson cloud contribution from pion and rho-meson, for which an\naccurate calculation using the meson nuclear spectral functions is used.\nSimilarly, the nucleonic contribution is evaluated in terms of a relativistic\nnucleon spectral function. Fair agreement with experiment is found for\ndifferent nuclei and the results show a sizeable contribution from the\nrenormalized meson cloud. In order to reproduce the experiment a novel element\nis introduced, consisting of a gradual energy loss of the incoming proton in\nits pass through the nucleus which produces a strong A dependence at x_1 large.",
