Drag force in SYM plasma with B field from AdS/CFT

TL;DR

This paper studies how a non-zero B-field affects the drag force experienced by a quark or monopole in N=4 super Yang-Mills plasma using AdS/CFT, revealing corrections to string configurations and forces.

Contribution

It introduces the effects of a NSNS B-field on drag force calculations in SYM plasma within the AdS/CFT framework, providing new insights into external field influences.

Findings

Drag force receives corrections due to the B-field.

String tail configurations are altered by the B-field.

External electromagnetic fields impact the string dynamics.

Abstract

We investigate drag force in a thermal plasma of N=4 super Yang-Mills theory via both fundamental and Dirichlet strings under the influence of non-zero NSNS $B$-field background. In the description of AdS/CFT correspondence the endpoint of these strings correspondes to an external monopole or quark moving with a constant electromagnetic field. We demonstrate how the configuration of string tail as well as the drag force obtains corrections in this background.
