Photons and dileptons are pristine probes of the hot and dense medium formed in heavy-ion collisions, since, once produced, they traverse the fireball undistorted. Dilepton invariant-mass spectra are the only known observable which enable a direct access to an in-medium spectral function, in the vector channel. In the vacuum, and at low mass (M<1.5GeV), the vector spectral function is...
