For increased sensitivity, we subtract out the vacuum contributions. With a saturation scheme often considered in the literature, we find these subtracted sum rules to be unstable. It indicates the importance of other contributions neglected in the saturation scheme. These include more Landau singularities at low energy, additional operators in the medium, and possibly the in-medium width of the rho meson.", "revisions": [ { "version": "v2", "updated": "2001-05-31T09:30:07.000Z" } ], "analyses": { "keywords": [ "qcd sum rules", "nuclear matter", "saturation scheme", "rho meson channel", "in-medium width" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
