Associated production of $J/\psi$ plus $Z(W)$ in the improved color evaporation model using the parton Reggeization approach

Abstract

In the article, we study the associated production of prompt $J/\psi$ mesons and $Z(W)$ bosons 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 $J/\psi$ and $Z(W)$ hadroproduction via the single and double parton scattering mechanisms using the set of model parameters that have been obtained early for the description of single and double prompt $J/\psi$ production at the LHC energies. The numerical calculations are realized using the Monte-Carlo event generator KaTie. The calculation results are compared with the data at the energies $\sqrt{s} = 7 \mbox{ and } 8$ TeV and we make predictions for the energy $\sqrt{s}=13$ TeV for $J/\psi$ plus $Z(W)$ and ${\rm Y}$ plus $Z/W$ at the $\sqrt{s} = 8 \mbox{ and } 13$ TeV associated productions.
