Glueball-Induced Partonic Energy Loss in Quark-Gluon Plasma
Dong-Pil Min, Nikolai Kochelev
TL;DR
This paper investigates how interactions with scalar and pseudoscalar glueballs contribute significantly to partonic energy loss in quark-gluon plasma, potentially explaining observed jet-quenching phenomena.
Contribution
It introduces a novel mechanism for partonic energy loss involving glueball interactions, highlighting their importance above the deconfinement temperature.
Findings
Glueball interactions significantly contribute to jet-quenching.
The mechanism may explain observed jet suppression in experiments.
Energy loss via glueballs is comparable to other known mechanisms.
Abstract
We discuss the energy loss of energetic parton jets in quark-gluon plasma above the deconfinement temperature by the interaction with scalar and pseudoscalar glueballs. It is shown that the loss by this mechanism is quite important and may play the important role of the observed jet-quenching.
