      abstract     = {The invariant differential cross section of inclusive
                      $\omega (782)$ meson production at midrapidity ($|y|<0.5$)
                      in pp collisions at $\sqrt{s}=7\,\hbox {TeV}$ was measured
                      with the ALICE detector at the LHC over a transverse
                      momentum range of $2< p_{\mathrm {T}}< 17\,\hbox {GeV}/c$.
                      The $\omega $ meson was reconstructed via its $\omega
                      \rightarrow \pi ^+\pi ^-\pi ^0$ decay channel. The measured
                      $\omega $ production cross section is compared to various
                      calculations: PYTHIA 8.2  Monash 2013 describes the data,
                      while PYTHIA 8.2 Tune 4C overestimates the data by about
                      50\%. A recent NLO calculation, which includes a model
                      describing the fragmentation of the whole vector-meson
                      nonet, describes the data within uncertainties below
                      $6\,\hbox {GeV}/c$, while it overestimates the data by up to
                      50\% for higher $p_{\mathrm {T}}$. The $\omega /\pi ^0$
                      ratio is in agreement with previous measurements at lower
                      collision energies and the PYTHIA calculations. In addition,
                      the measurement is compatible with transverse mass scaling
                      within the measured $p_{\mathrm {T}}$ range and the ratio
                      is constant with $C^{\omega /\pi ^{0}}= 0.67 \pm 0.03 \text
                      {~(stat)~} \pm 0.04 \text {~(sys)~}$ above a transverse
                      momentum of $2.5\,\hbox {GeV}/c$.},
