Description
The angular distributions of Drell-Yan lepton pairs allow to determine precisely the dynamics of vector boson production in quantum chromodynamics. The dependence of the angular coefficients on the transverse momentum of the $J/\psi$ meson was obtained at the energy of the second stage of the SPD experiment using the Pythia generator. The $J/\psi$ mesons produced in $pp$ collisions at $\sqrt{s_{NN}} = 27$ GeV and decaying into a pair of muons were used in the analysis. Machine learning (ML) methods were applied for the selection of decay muons.
