Zheng Xiaoping, Li Jiarong, Liu Lianggang, Guo Shuohong
TL;DR
This paper introduces a relaxation-time approach to analyze collisionless quark-gluon plasma, revealing damping rates and mechanisms, with transverse modes damping more strongly than longitudinal ones.
Contribution
The paper develops a novel relaxation-time method specifically for collisionless quark-gluon plasma, providing new insights into damping mechanisms and rates.
Findings
Damping rate of order g^2 T
Plasmon scattering as damping mechanism
Stronger damping for transverse modes
Abstract
We present an effective relaxation-time theory to study the collisionless quark-gluon plasma. Applying this method we calculate the damping rate to be of order and find plasmon scattering is the damping mechanism. The damping for the transverse mode is stronger than the longitudinal one.
