PHENIX measurements of high transverse momentum (pT ) identified hadrons in d+Au and Au+Au collisions are presented. The nuclear modification factors (RdA and RAA) for π0 and ƞ are found to be very consistent in both collision systems, respectively. Using large amount of p + p and Au+Au datasets, the fractional momentum loss (Sloss) and the path-length dependent yield of π0 in Au+Au collisions are obtained. The hadron spectra in the most central d+Au and the most peripheral Au+Au collisions are studied. The spectra shapes are found to be similar in both systems, but the yield is suppressed in the most peripheral Au+Au collisions.
