Abstract:

We report results on a feasibility study of measuring the properties of φ (1020) resonance in collisions of bismuth nuclei at an energy of 9.2 GeV using the MPD detector at the NICA collider. Model calculations of heavy nuclei collisions and the secondary particles — the MPD material interaction have been performed for the φ (1020) → K⁺ + K^- decay. The dependencies of the process’es key parameters on the transverse momentum for different intervals of centrality of bismuth nuclei collisions were obtained in the rapidity range from -0.5 to +0.5. The evaluations of the mass resolution, detection efficiency of the MPD detector and the transverse momentum spectra for the φ (1020) resonance were made. The sample size of bismuth nuclei collision data that allowed the φ (1020) resonance properties to be reconstructed with a sufficiently good accuracy to conduct a study of the φ (1020) meson production was estimated.
