description: A special form of matter â quark-gluon plasma â can appear in collisions of heavy nuclei at ultrahigh energies. One of the most important signs of its occurrence in nuclear collisions is the elliptic flow â the azimuthal anisotropy of the momentum of particles born in the region of the expected appearance of quark-gluon plasma. This work is devoted to the measurement of elliptic flow of Ï0-mesons in U+U collisions at an energy 193 GeV/nucleon based on experimental data obtained in the PHENIX experiment. The first chapter introduces the basic concepts and explanations of some physical phenomena. The second chapter is devoted to various calibrations of detectors, which are necessary for further correct measurement of elliptic flow. In the third chapter, the calculation and correction of the values necessary for calculating elliptic flow are performed. In the fourth chapter, elliptic flows of Ï0-mesons are calculated. In this work, elliptic flows of Ï0-mesons in U+U collisions at an energy 193 GeV/nucleon were obtained. The dependencies of elliptic flows on the transverse momentum of Ï0-mesons were constructed for various ranges of centrality of nuclear-nuclear collisions.
