Query: Measurement of high-pT hadrons at RHIC-PHENIX   Measurements from the RHIC experiments show a strong suppression in the yield
of high-p$_\mathrm{T}$ single hadrons and a clear reduction in strength of the
di-jet signal in two-hadron azimuthal-angle correlation functions in central
Au+Au collisions at RHIC. These measurements should provide direct information
on the properties of the medium within which hard-scattered partons propagate.
The PHENIX preliminary results on single high-p$_\mathrm{T}$ hadron production
and on particle azimuthal correlations are shown. The properties of the medium
created in relativistic heavy ion collisions are discussed based on the
results.
