Viscosity and jet quenching from holographic model

TL;DR

This paper uses a holographic model to study how fundamental flavors affect the shear viscosity and jet-quenching in the quark-gluon plasma, providing insights into strongly coupled plasma dynamics.

Contribution

It introduces a backreacted holographic model to compute flavor contributions to viscosity and jet quenching, advancing understanding of plasma properties.

Findings

Flavor backreaction increases shear viscosity.

Flavor effects modify jet-quenching parameter.

Results align with expectations from strongly coupled plasma theories.

Abstract

We consider the backreaction of the fundamental flavor degrees of freedom on the AdS$_5$-Schwarz background, and calculate their contributions to the shear viscosity and jet-quenching parameter of the thermal quark-gluon plasma.
