Chin-Hao Chen (for the PHENIX collaboration)
TL;DR
The PHENIX experiment systematically studied high transverse momentum parton energy loss and jet modifications in hot nuclear matter, using various observables and control measurements to understand medium effects in heavy-ion collisions.
Contribution
This work introduces a comprehensive analysis of jet quenching and medium modifications in heavy-ion collisions using multiple experimental observables.
Findings
Evidence of significant parton energy loss at high pT.
Observation of jet-induced medium modifications such as the ridge and shoulder.
Baseline measurements in d+Au collisions to distinguish cold nuclear matter effects.
Abstract
By tuning several experimental observables, such as momentum and reaction plane, the PHENIX experiment has performed a systematic study of high 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 control of cold nuclear matter effect.
