Global properties of relativistic heavy-ion collisions proved by PHENIX

We report recent experimental results of elliptic flows (v2), event-by-event fluctuations and Bose-Einstein correlations (HBT) of identified hadrons measured by PHENIX detector at low transverse momentum (pT<∼2 GeV/c) and mid-rapidity (|η|<0.35) region. We focus on results observed in Au+Au collision at , but results from Au+Au at 63 GeV and Cu+Cu at 63 and 200 GeV are also reported. These observables give us detailed insights into the properties of the space-time evolution such as the order of the phase transition and the collective dynamics of the hot-and-dense matter.
