【 摘 要 】
PHENIX measurement of the fractional momentum loss (δpT/pT) of high pTidentified hadrons are presented. The δpT/pTof high pTπ0which are computed from 39 GeV Au+Au up to 2.76 TeV Pb+Pb are found to vary by a factor of six. We plotted the δpT/pTagainst several global variables, Npart, Nqpand dNch/dη, and found global features. It was found that 200 GeV Au+Au points are merging into the central 2.76 TeV Pb+Pb points when plotting δpT/pTagainst dNch/dη.
