description: This work is devoted to the study of the deuteron yield in proton collisions at the energies of the NIKA collider under construction (JINR, Dubna) âs = 8 - 26 GeV in various coalescence models. The results obtained using PYTHIA8 were compared with experimental data obtained at U-70 accelerators (IHEP, Protvino) at an energy of âs = 11.4 GeV and Tevatron (FNAL, Chicago) at an energy of âs = 23.4 GeV. In the framework of this work, various coalescence models were studied that describe the formation of deuterons from nucleons by incorporating them into the Monte Carlo physical event generator PYTHIA8. We analyzed the magnitude and shape of the probability of coalescence as a function of the difference in the momenta of nucleons for various coalescence models, and a number of new dependencies for this function were added. Various forms of dependence of the probability function of coalescence make it possible to determine the probability and dynamics of the coalescence process. The parameters of the new coalescence models included in PYTHIA8 were selected to best describe the U-70 data (IHEP, Protvino). For these models, predictions were made for NIKA (JINR, Dubna). The following were carried out: studies of the dependence of the probability function of nucleon coalescence in deuteron, comparison of the results obtained using PYTHIA8 with the available experimental data, and predictions were made for NIKA (JINR, Dubna).
