Jet Quenching via Gravitational Radiation in Thermal AdS

TL;DR

This paper demonstrates that gravitational radiation effects in AdS/CFT, amplified by high Lorentz factors, can dominate jet energy loss mechanisms in a strongly coupled thermal medium, providing new insights into holographic jet quenching.

Contribution

It introduces the significance of gravitational radiation effects in holographic jet quenching, highlighting their amplification at high Lorentz factors and their dominance over other energy loss processes.

Findings

Gravitational radiation effects are magnified by large Lorentz factors.

These effects can dominate jet energy loss in holographic models.

Relativistic jets mainly lose energy through longitudinal drag in a thermal medium.

Abstract

We argue that classical bulk gravitational radiation effects in AdS/CFT, previously ignored because of their subleading nature in the 1/Nc-expansion, are magnified by powers of large Lorentz factors gamma for ultrarelativistic jets, thereby dominating other forms of jet energy loss in holography at finite temperature. We make use of the induced gravitational self-force in thermal AdS5 to estimate its effects. In a thermal medium, relativistic jets may loose most of their energy through longitudinal drag caused by the energy accumulated in their nearby field as they zip through the strongly coupled plasma.
