Double-parton scattering effects in double charm production within gluon fragmentation scenario

We discuss charm D 0D 0 meson-meson pair production in the forward rapidity region related to the LHCb experimental studies at √ s = 7 TeV. We consider double-parton scattering mechanisms of double cc¯ production and subsequent standard cc → D 0D 0 scale-independent hadronization as well as new double g and mixed gcc¯ production mechanisms with gg → D 0D 0 and gc → D 0D 0 scale-dependent hadronization. The new scenario with gluon fragmentation components results also in a new single-parton scattering mechanism of gg production which is also taken here into account. Results of the numerical calculations are compared with the LHCb data for several correlation observables. The new mechanisms lead to a larger cross sections and to slightly different shapes of the calculated correlation observables.
