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 $2.5\,\hbox {GeV}/c$.},
