As reported earlier, a significant excess of the e+e- pair yield over the expectation from hadron decays is observed. The improved mass resolution of the present data set, recorded with the upgraded CERES experiment at the CERN-SPS, allows for a comparison of the data with different theoretical approaches. The data clearly favor a substantial in-medium broadening of the rho spectral function over a density- dependent shift of the rho pole mass. The in-medium broadening model implies that baryon induced interactions are the key mechanism to in-medium modifications of the rho-meson in the hot fireball at SPS energy."@en . "380212" . . .
