Description
We study associated production of heavy quarkonia and D mesons in the improved color evaporation model using the high-energy factorization as it is formulated in the parton Reggeization approach. The last one is based on the modified Kimber-Martin-Ryskin-Watt model for unintegrated parton distribution functions and the effective field theory of Reggezied gluons and quarks, suggested by L.N. Lipatov. We predict cross section for associated J/ψ or Υ and D hadroproduction via the single and double parton scattering mechanisms using the set of model parameters which have been obtained early for the description of single and double J/ψ and Υ production at the LHC energies [1]. The numerical calculations are realized using the Monte-Carlo event generator KaTie. The calculation results are compared with the LHC data at the energies √s = 7 and 8 TeV.
