Abstract
In this paper we study the signal-to-background ratios for the \(J{\text{/}}\psi \)-meson associated and direct photon main production processes at the energies of SPD NICA experiment using the Monte Carlo generator PYTHIA8. We extract the set of kinematic constraints allowing to improve signal-to-background ratios. We compare the results of our simulation for the direct photon spectra in different intervals of \({{p}_{T}}\) and \({{x}_{F}}\) with the experimental data and present the predictions for signal-to-background ratios in direct photon production at the NICA energy of \(\sqrt s = 27\) GeV.
