    <description descriptionType="Abstract">&lt;p&gt;The invariant differential cross section of inclusive     $\omega \left(782\right)$   meson production at midrapidity (    $|y|&amp;lt;0.5$  ) in pp collisions at     $\sqrt{s}=7\phantom{\rule{0.166667em}{0ex}}\text{TeV}$   was measured with the ALICE detector at the LHC over a transverse momentum range of     $2&amp;lt;{p}_{T}&amp;lt;17\phantom{\rule{0.166667em}{0ex}}\text{GeV}/c$  . The     $\omega $   meson was reconstructed via its     $\omega \to {\pi }^{+}{\pi }^{-}{\pi }^{0}$   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     $6\phantom{\rule{0.166667em}{0ex}}\text{GeV}/c$  , while it overestimates the data by up to 50% for higher     ${p}_{T}$  . 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     ${p}_{T}$   range and the ratio is constant with     ${C}^{\omega /{\pi }^{0}}=0.67±0.03\phantom{\rule{0.333333em}{0ex}}\text{(stat)}\phantom{\rule{0.333333em}{0ex}}±0.04\phantom{\rule{0.333333em}{0ex}}\text{(sys)}\phantom{\rule{0.333333em}{0ex}}$   above a transverse momentum of     $2.5\phantom{\rule{0.166667em}{0ex}}\text{GeV}/c$  .&lt;/p&gt;</description>
