| Abstract | In connection with the claim made at Quark Matter 2005 Conference that Brown-Rho scaling is ruled out by NA60 data we consider dimuon production from semi-central In+In collisions in a full dynamical model. It is shown that allowing only for density-dependent $\rho$-mass modification reasonably reproduces the shape of dimuon invariant mass spectra. Additional inclusion of the temperature-dependent modification factor shifts the spectra maximum towards lower invariant masses making calculation results incompatible with data. Further study is needed to disentangle BR dropping $\rho$ mass scaling and strong broadening. |
