Highlights from NA60

Understand

NA60 measured dimuon production in p-A and In-In collisions at the CERN SPS.

• This paper presents a high statistics measurement of $\phi$ 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 $\phi$ puzzle.
