  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 hadronic matter. A preliminary
measurement of the $\phi$ and $\omega$ differential cross sections was
performed by the ALICE experiment in pp collisions at $\sqrt{s}=7$ TeV, through
their decay in muon pairs. The $p_{\rm T}$ and rapidity regions covered in this
analysis are $p_{\rm T}>1$ GeV$/c$ and $2.5 < y < 4$.
