Abstract: NA60 is a CERN SPS experiment that studied dimuon production in In-In collisions at 158 A•GeV per nucleon.More recently proton nucleus collisions have also been investigated in order to provide a reference for heavy ion studies.Some of the most important results obtained by the experiment are the first measurement of the ρ spectral function in nuclear collision and the study of its medium-induced modifications, the production of thermal muon pairs in the invariant mass region between the φ and the J/ψ, and the study of the J/ψ suppression.Recent results include further studies on the characterization of thermal pairs, the comparison of φ production in µ µ and KK channels (the φ puzzle) and the first measurement of cold nuclear matter effects on J/ψ production at 158 GeV, the same energy where the anomalous J/ψ suppression has been observed.
