Description

The azimuthal anisotropy on the particle emission is expected as a method to approach the characteristics of the deconfined quarks and gluons state (QGP) generation in the high-energy heavy-ions collisions. The azimuthal anisotropy is sensitive to the early stage and, is the observable that is affected by QGP properties. The behavior of anisotropy is consistent with the hydro-dynamical model for $p_{T}$ lower than 2GeV/c, but not for higher $p_{T}$. When there is QGP, parton lose their energy (jet quenching) and its energy loss is related to the pass length in the dense matter. In non-central collisions, this jet quenching makes an azimuthal anisotropy in the high $p_{T}$ region where the hard process is dominant. In this poster, we will present the status of detailed study for $p_{T}$ and centrality dependence of the azimuthal anisotropy for high $p_{T}$ (up to 8~10 GeV) charged hadrons in 200 GeV Au+Au collisions with RHIC-PHENIX. The relation of the pass length to the azimuthal anisotropy will be discussed.
