Elliptic flow for φ mesons measured by PHENIX

The systematic study of hadronic elliptic flow in various relativistic heavy ion collisions is important for the investigation initial geometry influence on quark gluon plasma characteristics. φ meson consists strange and antistrange quarks has a small interaction cross section with non-strange hadrons. Therefore, mesons are barely affected by late stage reflect detailed information about hot dense matter properties. Additionally, comparison to those charged hadrons will provide additional flavor dependence flow. PHENIX measured second order azimuthal anisotropy coefficients Cu+Au at √ S NN = 200 GeV U+U 193 midrapidity (| η | < 0.35). obtained data suggest scaling eccentricity participant nucleons Cu+Au, U+U, Au+Au collisions. Viscous hydrodynamic model iEBE-VISHNU provides simultaneous description data.
