  "abstract": "QCD sum rules are evaluated at finite nucleon densities and temperatures to determine the change of mass parameters for the lightest vector mesons $\\rho$, $\\omega$ and $\\phi$ in a strongly interacting medium. For conditions relevant for the starting experiments at HADES we find that the in-medium mass shifts of the $\\rho$ and $\\omega$ mesons are governed, within the Borel QCD sum rule approach, by the density and temperature dependence of the four-quark condensate. In particular, the variation of the strength of the density dependence of the four-quark condensate reflects directly the decreasing mass of the $\\rho$ meson and can lead to a change of the sign of the $\\omega$ meson mass shift as a function of the density. In contrast, the in-medium mass of the $\\phi$ meson is directly related to the chiral strange quark condensate which seems correspondingly accessible.",
