  "abstract": "Realistic vacuum $\\pi\\pi$ interactions are employed to investigate thermal $\\pi^+\\pi^-$ emission spectra from the late stages of heavy-ion reactions at ultrarelativistic energies. Hadronic in-medium effects, including many-body $\\rho$-meson spectral functions used earlier to describe the dilepton excess observed at CERN-SPS energies, are implemented to assess resulting modifications in relation to recent measurements of $\\pi^+\\pi^-$ invariant-mass spectra by the STAR collaboration in $p$-$p$ and $Au$-$Au$ collisions at $\\sqrt{s_{NN}}$=200 GeV. Statistical model estimates for the $\\rho^0/\\pi^-$ and $K^*/K$ ratios close to the expected thermal freezeout are also given.",
