Elliptic flow measurements with the PHENIX detector

In summary, elliptic flow measurements have been made with the PHENIX detector via two-particle azimuthal correlation functions. The measurements indicate relatively large differential and integral flow magnitudes. The differential flow v₂(p_t), v₂(cent) and v₂(p_t, cent) are found to increase with both the < p_t > of emitted hadrons, and with increasing impact parameter. The magnitude and the data trends are in good qualitative agreement with other flow measurements at RHIC[4]. They also show surprisingly good agreement with the results from hydrodynamic model calculations[10,11]. Further detailed analyses of PHENIX flow data are currently in progress and will be reported elsewhere[16].
