/ Abstract
The NA60 experiment at the CERN-SPS is devoted to the study of dimuon production in heavy-ion and proton-nucleus collisions. We present preliminary results from the analysis of Indium-Indium collisions at 158 GeV per nucleon. The topics covered are low mass vector meson production, J/ production and suppression, and the feasibility of the open charm measurement from the dimuon continuum in the mass range below the J/ peak. The study of dimuon production in heavy-ion collisions is generally considered to be one of the most powerful tools in the search for the phase transition between the normal nuclear matter and the Quark-Gluon Plasma phase, where the quarks and gluons are no longer confined into hadrons. The most intriguing findings of dilepton experiments working in this field have been: the excess in the production of dielectron pairs in the mass window 200–700 MeV/c 2 , (
