    "abstract": "The inclusive A(gamma,pi+ pi-)X reaction is studied theoretically. A sizeable\nenhancement of the cross section is found, in comparison with the scaling of\nthe deuteron cross section (sigma_deuteron * A/2). This enhancement is due to\nthe modifications in the nuclear medium of the gamma N ----\u003e pi pi N amplitude\nand the pion dispersion relation. The enhancement is found to be bigger than\nthe one already observed in the (pi,pi pi) reaction in nuclei.",
