Vector mesons are key probes of the hot and dense state of strongly interacting matter produced in heavy-ion collisions. Their dileptonic decay channel is particularly suitable for these studies, since dileptons have negligible final state interactions in QCD matter. A preliminary measurement of the φ and ω differential cross sections was performed by the ALICE experiment in pp collisions at √s = 7 TeV, through their decay in muon pairs. The pT and rapidity regions covered in this analysis are pT > 1 GeV/c and 2.5 < y < 4.

Abstract
Vector mesons are key probes of the hot and dense state of strongly interacting matter produced in heavy-ion collisions. Their dileptonic decay channel is particularly suitable for these studies, since dileptons have negligible final state interactions in QCD matter. A preliminary measurement of the φ and ω differential cross sections was performed by the ALICE experiment in pp collisions at √s = 7 TeV, through their decay in muon pairs. The pT and rapidity regions covered in this analysis are pT > 1 GeV/c and 2.5 < y < 4.
