    "abstract": "We investigate the modification of the pion-cloud in the nuclear medium and\nits effect on the nuclear Drell-Yan process. The pion\u0027s in-medium self-energy\nis calculated in a self-consistent delta-hole model, with particle-hole\ncontribution also included. Both the imaginary and real part of the pion\u0027s and\ndelta\u0027s self-energy are taken into account and related through a dispersion\nrelation assuring causality. The resulting in-medium pion light-cone momentum\ndistribution shows only a slight enhancement compared to the one of the free\nnucleon. As a consequence the ratio of the cross-section for Drell-Yan\nscattering on nuclear matter and nucleonic target is close to unity in\nagreement with experiment.",
