High image Parton Energy Loss from Jet Pair Correlation Observables in the PHENIX Experiment Original Research Article

By controlling several experimental observables, such as momentum and reaction plane, the PHENIX experiment has performed a systematic study of high pT parton energy loss in hot nuclear matter, as well as jet-induced medium modifications, such as the ridge and shoulder. Baseline d+Au measurements are also studied to provide the comparison as a control for cold nuclear matter effect.
