Abstract
The article considers the production of \({{\eta }_{{\text{c}}}}\) mesons at LHC energies using the parton Reggeization approach and the leading order perturbation theory of quantum chromodynamics. The hadronization of a quark–antiquark pair (\(c\bar {c}\)) in \({{{{\eta }}}_{{\text{c}}}}\) is described in the framework of nonrelativistic quantum chromodynamics and with the using of color evaporation model. The calculation results are compared with experimental data for the \({{\eta }_{{\text{c}}}}\) production cross section in proton–proton collisions obtained by the LHCb collaboration. Predictions have been made for the kinematic conditions of the LHCb and ATLAS collaboration experiments at an energy \(\sqrt s = \) 13 TeV.
期刊介绍：
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
