NA60 is a fixed target experiment at the CERN SPS studying dimuon production in different colliding systems: In-In at 158 A GeV incident energy and p-A collisions at 158 and 400 GeV. A strong excess of dimuon pairs has been observed in the region of the invariant mass spectrum below the J/?. The high resolution of the NA60 detector allowed to measure the in-medium modifications of the ? spectral function and to clarify the origin of the dimuon excess in the region above the phi. The J/? suppression has been studied in In-In and p-A collisions at 158 GeV incident energy. The latest results on these topics are addressed in this paper.

Abstract
NA60 is a fixed target experiment at the CERN SPS studying dimuon production in different colliding systems: In-In at 158 A GeV incident energy and p-A collisions at 158 and 400 GeV. A strong excess of dimuon pairs has been observed in the region of the invariant mass spectrum below the J/?. The high resolution of the NA60 detector allowed to measure the in-medium modifications of the ? spectral function and to clarify the origin of the dimuon excess in the region above the phi. The J/? suppression has been studied in In-In and p-A collisions at 158 GeV incident energy. The latest results on these topics are addressed in this paper.File in questo prodotto:
