✦ Synopsis

Within the next-to-leading order (NLO) perturbative QCD (pQCD) parton model, suppression of away-side hadron spectra associated with a high p T photon due to parton energy loss is shown to provide a complete tomographic picture of the dense matter formed in high-energy heavyion collisions at RHIC. Dictated by the shape of the γ-triggered jet spectrum in NLO pQCD, hadron spectra at large z T = p h T /p γ T >
