Feasibility Studies Using Enhanced Particle Production: An Afterburner for the MPD Experiment / D.Flusova, P.Parfenov, V.Troshin, A.Taranenko // Физика элементарных частиц и атомного ядра. Письма. – 2026. – Т. 23, № 5. – P. 477.

Anisotropic flow and global polarization are the key observables for characterizing properties of strongly-interacting matter in relativistic heavy-ion collisions at NICA energies (*%s&sub(NN) = 2.5−11 GeV). A significant challenge for the MPD experiment is achieving the necessary statistical precision for these measurements, particularly for direct photons, *f mesons, *S and *L hyperons. To address this issue, we have developed a statistical event resampling afterburner package. This tool was validated using simulated Xe + Xe collisions at *%s&sub(NN) =2.87 GeV generated with the UrQMD model. The application of this afterburner package resulted in a substantial enhancement of the resolution of the directed (v&sub(1)) and elliptic (v&sub(2)) flow of *L hyperons, in addition to their global polarization. This paper confirms the method’s utility for the future feasibility studies and data analysis in the MPD experiment.
