Inclusive $\Dzero$ mesons (including also $\Dzero$ mesons from beauty-hadron decays) in $|y|< 0.5$ in pp collisions at $\sqrts =5.02 \tev$, from the analysis without decay-vertex reconstruction, compared to FONLL pQCD calculations  with the $\mathrm{B} \rightarrow \mathrm{D} + X$ decay kinematics from the EvtGen package  (grey boxes). The contributions of prompt $\Dzero$ from FONLL (red) and $\Dzero$ from B-meson decays from FONLL+EvtGen (blue) are also shown separately. The vertical error bars and the empty boxes represent the statistical and systematic uncertainties, respectively.
