Subject: Determination of Vector Meson Properties in Dense Matter via Relativistic Nuclear Collisions

CERN experiment NA60 has measured low-mass muon pair production in In-In collisions at 158 GeV/nucleon with unprecedented precision. The data is reproduced very well by a dynamical model which also describes hadron spectra and two-particle HBT correlations. The data is consistent with the properties of rho and omega vector mesons at finite temperature and density as deduced from empirical forward scattering amplitudes. In particular, these mesons have greatly broadened widths but no significant shift in mass.
