Abstract
In this proceeding we discuss different mechanisms of open-heavy flavor meson production which contribute to inclusive and single diffractive cross-sections. For the case of inclusive production we demonstrate that the three-Pomeron fusion is significant for the $D$-meson production in the kinematics of small transverse momenta $p_{T}$, as well as in large-multiplicity events. Its inclusion allows to improve significantly the description of experimental data. We also analyzed the diffractive production and found that due to gap survival factors it constitutes 0.5\textendash 2 per cent of the inclusive production. The expected dependence on event multiplicity in this channel is significantly milder than for inclusive case.

List of changes
Below we provide detailed changes made in the resubmitted version:
REFEREE:
General observation:
Fig. 1, assuming the solid line is for 2-apomeron and dashed line for 2 and 3-pomeron as described in the figure, I don't see the improvement at small P_T. The dashed curve clearly over predicts the data. This doesn't support the conclusion.
AUTHORS:
In the previous version we had mistakenly set the labels in the left panel of the Figure 1. The dashed line in this plot corresponds to 2-pomeron only contribution, whereas solid line is a sum of 2- and 3-pomeron contributions. The caption of the Figure correctly claims that 3-pomeron contribution is negative, so its inclusion decreases the total result and improves agreement with data (as we can see from the plot, the solid line is closer to the data than the dashed one).
In order to correct this issue, in the resubmitted version we corrected the labels in the left panel of the Figure 1.
