    "abstract": "The mass shift and width broadening of rho-mesons produced in heavy ion\ncollisions is estimated using general formulae which relate the in-medium mass\nshift of a particle to the real part of the forward scattering amplitude of\nthis particle on constituents of the medium and the width broadening to the\ncorresponding cross section. It is found that the mass increases by some tens\nof MeV but, more importantly, the width becomes large, increasing by several\nhundred MeV at beam energies of a few GeV per nucleon and by twice that amount\nat beam energies of about a hundred GeV per nucleon.",
