    "abstract": "The influence of a dropping sigma-meson mass on previously calculated\nin-medium pion-pion correlations in the J=I=0 (sigma-meson) channel is\ninvestigated. It is found that the invariant-mass distribution around the\nvacuum threshold experiences a further strong enhancement with respect to\nstandard many-body effects. The relevance of this result for the explanation of\nrecent $A(\\pi,2\\pi)X$ data is pointed out.",
