【 摘 要 】

Strangeness enhancement is one of the possible signatures of the Quark Gluon Plasma formation and can be accessed through the measurement of φ meson production with respect to ρ and ω mesons. Vector mesons can be detected through their decays into muon pairs with the ALICE muon spectrometer. We present transverse momentum spectra of φ and ρ + ω mesons in the rapidity range 2.5
