【 摘 要 】

We present results on the low mass dimuon analysis in pp, p-Pb and Pb-Pb collisions. In pp collisions at √s = 2.76 TeV the φ differential cross section as a function of the transverse momentum has been measured, while the φ yield and the nuclear modification factor RpPbat forward and backward rapidity have been measured in p-Pb collisions at √sNN= 5.02 TeV. The BRσφ/BRσρ+ BRσωratio and the φ nuclear modification factor RAAhave been measured in Pb-Pb collisions at √sNN= 2.76 TeV in the intermediate pTregion 2 TTrange at midrapidity in the hadronic decay channel φ → KK.
