$\pt$-differential production cross sections of prompt and non-prompt $\Dzero$ (top left panel), $\Dplus$ (top right panel), and $\Ds$ (bottom panel) mesons compared to predictions obtained with GM-VFNS calculations . For the non-prompt $\Dzero$ and $\Dplus$ mesons the one-step (green) and two-step (purple) approaches, describing the transition from the beauty quark to the charm meson, are reported. The measurement of prompt $\Dzero$ mesons is the one reported in Ref. , with updated decay BR as discussed in the text.
