Highlights from NA60

Abstract

NA60 measured dimuon production in p-A and In-In collisions at the CERN SPS. This paper presents a high statistics measurement of $\ddot{I}•$ meson production in In-In collisions at 158 AGeV. Both the transverse momentum, rapidity, decay angular distributions and the absolute yield were measured as a function of centrality. The results are compared to previous measurements in order to shed light on the long standing $\ddot{I}•$ puzzle. In addition, highlights on $\hat{I}\cdot$ meson production and on the dimuon excess below the J/$\ddot{I}ˆ$ mass are presented.
