Production of $\omega(782)$ in pp collisions at $\sqrt{s}$ = 7 TeV

The production of $\omega(782)$meson has been measured at mid-rapidity in pp collisions at $\sqrt{s}$ = 7 TeV with the ALICE detector at the Large Hadron Collider (LHC). The particles are reconstructed in the $\omega\rightarrow\pi^{0}\pi^{+}\pi^{-}$ decay channel. A data sample with an integrated luminosity of 6 nb$^{-1}$ has been used to measure the invariant differential cross section of the $\omega$ meson and the $p_{T}$-differential $\omega /\pi^{0}$ ratio in the transverse momentum range $2<$p_{T}$<17$ GeV/$c$. The measured cross section and the $\omega /\pi^{0}$ ratio are found to be in agreement with predictions of PYTHIA and PHOJET events generators. Furthermore, the $\omega /\pi^{0}$ ratio is consistent with previous measurements by other experiments at lower energies within uncertainties.
