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.
