Invariant cross section of $\omega$ meson production at mid-rapidity in pp collisions at $\sqrt{s}=7$ TeV compared to theoretical predictions. The statistical and systematic uncertainties are represented by vertical bars and boxes, respectively. A Levy-Tsallis function was used to parametrise the spectrum. The predictions are obtained using PYTHIA 8.2 with the Monash 2013 and 4C tunes. Furthermore, a NLO calculation incorporating a model dedicated to describe vector-meson fragmentation is shown, where the band denotes the uncertainty of the scale $\mu$, which was used for factorisation, renormalisation and fragmentation. In the bottom panel, the ratios of the theoretical estimates to the Levy-Tsallis fit of the measurement are shown; the ratio of the data to the Levy-Tsallis fit is also presented.
