Production ratio $\omega$/\piz in \pp and \pPb collisions calculated using the $\omega$ meson production measurements and the corresponding charged  and neutral pion  references, respectively. The charged pion reference was scaled up by 3.3\% (see text for details). Also shown are two predictions from simulations per collision system, with bands representing their statistical uncertainties, as well as a $m_\text{T}$ scaling curve, which converges towards a high-\pt constant (C) fitted to the ratio for \pt $>$ 4 \GeVc.
