Description
In our work, we consider the process of associated charmonium and jet production.
One of the reasons why it is difficult to study charmonium hadronization process is
the non-perturbative nature of this state, which can only be described within the
framework of phenomenological models. Moreover, a double parton scattering
(DPS) contribution can be dominating in certain kinematic regions of associated
charmonium and jet production. Nevertheless, in order to estimate a potential
contribution of DPS we have to calculate a single parton scattering (SPS)
contribution.
The purpose of our work is theoretical prediction of the charmonium production
cross section together with a single hard hadron jet in proton-proton collisions in a
parton Reggeization approach (PRA). An improved color evaporation model
(ICEM) was chosen as a hadronization model. Our theoretical predictions
(transverse momenta, rapidity, invariant mass and azimuthal distributions) is
calculated at Large Hadron Collider (LHC) energies in the KaTie -- parton-level
event generator for hadron scattering processes with off-mass-shell partons.
