Heavy quarks in the presence of higher derivative corrections from AdS/CFT

TL;DR

This paper investigates how higher derivative corrections in AdS/CFT influence heavy quark behavior in a hot plasma, revealing increased energy loss and shorter dissociation lengths as coupling parameters grow.

Contribution

It provides a detailed analysis of finite coupling corrections on heavy quark energy loss and dissociation length within the gauge-string duality framework.

Findings

Energy loss of heavy quarks increases with higher derivative corrections.

Dissociation length of quark-antiquark pairs decreases as higher curvature coupling parameters increase.

Higher derivative corrections significantly affect quark dynamics in a thermal plasma.

Abstract

We use the gauge-string duality to study heavy quarks in the presence of higher derivative corrections. These corrections correspond to the finite coupling corrections on the properties of heavy quarks in a hot plasma. In particular, we study the effects of these corrections on the energy loss and the dissociation length of a quark-antiquark pair. We show that the calculated energy loss of heavy quarks through the plasma increases. We also find in general that the dissociation length becomes shorter with the increase of coupling parameters of higher curvature terms.
