Probing strongly coupled anisotropic plasmas from higher curvature gravity

TL;DR

This paper investigates the properties of strongly coupled anisotropic plasmas using a higher curvature gravity dual, analyzing how anisotropy and higher derivative corrections influence key observables like drag force and photon production.

Contribution

It introduces a five-dimensional AdS-axion-dilaton gravity model with Gauss-Bonnet corrections to study anisotropic plasmas and computes multiple observables to understand their behavior.

Findings

Higher derivative corrections affect plasma observables.

Anisotropy modifies drag force and jet quenching.

Results are compared with previous isotropic models.

Abstract

We consider five-dimensional AdS-axion-dilaton gravity with a Gauss-Bonnet term and use a black brane solution displaying spatial anisotropy as the gravity dual of a strongly coupled anisotropic plasma. We compute several observables relevant to the study of the plasma, namely, the drag force, the jet quenching parameter, the quarkonium potential and the thermal photon production. The effects of higher derivative corrections and of the anisotropy are discussed and compared with previous results.
