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
DD-meson
production in the kinematics of small transverse momenta
p_{T}pT,
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 percent of the inclusive production. The expected
dependence on event multiplicity in this channel is significantly milder
than for inclusive case.
