One of the key tasks of the PHENIX experiment is studying the properties of the quark–gluon plasma (QGP). An efficient method for studying the properties of the QGP is measuring the azimuthal anisotropy of particle production in ultrarelativistic collisions of heavy ions. The azimuthal anisotropy is characterized by the coefficients of the Fourier transform of the function of particle distribution over the azimuthal angle. The measurement of the second coefficient of the Fourier transform (\({{v}_{2}}\)), which is called the elliptic flow, makes it possible to investigate the collective behavior of nuclear matter and, thus, to study the QGP properties. In this study, a review of the recent results of measurement of hadron elliptic flows as a function of the transverse momentum and centrality of nuclei collisions in the PHENIX experiment is presented. The data of measured values of \({{v}_{2}}\) for neutral and charged hadrons in the Cu + Au and Au + Au collisions at energy \(\sqrt {{{s}_{{NN}}}} \) = 200 GeV are presented.
期刊介绍:
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
