Description

The hadroproduction of D^0, D^*, D^+ and D_s mesons is calculated in the LO of Parton Reggeization Approach, using the KMR[1] set of unintegrated PDFs of the proton to take into account the factorisable effects of initial-state radiation, and the set of fragmentation functions [2]. The obtained accuracy of the description of the recent Tevatron (sqrt(S)=1960 GeV) and LHC (sqrt(S)=1960 GeV) data is comparable with the accuracy of the NLO Collinear Parton Model calculations of the Ref. [3]. This work continues the series of our studies of the production of jets [4] and heavy quarks [5,6,7] in the high energy hadron collisions, exploiting the kT-factorization and parton Reggeization hypothesis.
