We expose the role of collisional energy loss on high p T photon data measured by PHENIX collaboration by calculating photon yield in jet–plasma interaction. The phase-space distribution of the participating jet is dynamically evolved by solving Fokker–Planck equation. It is shown that the data are reasonably well reproduced when contributions from all the relevant sources are taken into account. Predictions at higher beam energies relevant for LHC experiment have been made.
