    "abstract": "We analize two reactions: the electroproduction at small x and the Drell-Yan\nproduction by protons on nuclei. We show that nuclear shadowing in\nelectroproduction is larger if the virtuality of inter- mediate hadrons is\nproperly taken into account. In the Drell-Yan production, initial state\ninteractions of fast partons are included. With this input, the excess pion\ncontribution improves the description of data for both reactions.",
