Lorentz-invariant $\omega$ meson production cross section in \pp (open markers) and \pPb (closed markers). Statistical uncertainties are represented by vertical error bars, while boxes show the systematic uncertainties. Furthermore shown are \LT parametrizations of the two cross sections and two predictions from simulations of the $\omega$ meson production per collision system. The lower panels contain the ratios of the data and simulations to the parametrization of the data points in the respective collision system. A gray box in each ratio panel depicts the normalization uncertainty of the visible minimum bias cross section.
