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 rho 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 phi and the J/psi, and the study of the J/psi suppression. Recent results include further studies on the characterization of thermal pairs, the comparison of phi production in µµ and KK channels (the phi puzzle) and the first measurement of cold nuclear matter effects on J/psi production at 158 GeV, the same energy where the anomalous J/psi suppression has been observed.

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 rho 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 phi and the J/psi, and the study of the J/psi suppression. Recent results include further studies on the characterization of thermal pairs, the comparison of phi production in µµ and KK channels (the phi puzzle) and the first measurement of cold nuclear matter effects on J/psi production at 158 GeV, the same energy where the anomalous J/psi suppression has been observed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
