Invariant mass (mass-difference) distributions of $\Dzero$, $\Dplus$ ($\Dstar$), and charge conjugates, candidates in three $\ptD$ intervals for pp collisions at $\s$ = 5.02 TeV (top row) and \pPb collisions at $\snn$ = 5.02 TeV (bottom row). The curves show the fit functions applied to the distributions. For the $\Dzero$, the dashed line represents the combinatorial background including the contribution of reflection candidates (see ).
