PHENIX results on the $\sqrt{s_\mathrm{NN}}$ dependence of jet quenching
Christoph Baumann (for the PHENIX Collaboration)
TL;DR
The PHENIX experiment investigates how jet quenching varies with collision energy and system size, providing insights into parton energy loss in quark-gluon plasma across different energies and nuclei.
Contribution
This study presents new measurements of jet quenching dependence on collision energy and system size, extending understanding of parton energy loss mechanisms.
Findings
Jet quenching observed at 200 GeV in Au+Au collisions.
Support for parton energy loss in Cu+Cu collisions at 200 GeV.
Onset of jet quenching studied across three energies in Cu+Cu collisions.
Abstract
The PHENIX experiment has established jet quenching at a center-of-mass energy of 200 GeV in Au+Au collisions. Recent measurements of Cu+Cu collisions at the same center-of-mass energy support a parton energy loss scenario. Furthermore, the onset of jet quenching was studied in Cu+Cu collisions for three center-of-mass energies 22.4, 62.4 and 200 GeV.
