Transport properties of baryon rich back-reacted thermal plasma with finite 't Hooft coupling correction

TL;DR

This paper uses holography to analyze how baryon density, finite 't Hooft coupling, and higher derivative corrections affect transport properties like drag force, jet quenching, and energy loss in a thermal plasma.

Contribution

It introduces a detailed holographic model incorporating Gauss-Bonnet corrections and baryon density to study various transport phenomena in a strongly coupled plasma.

Findings

Drag force and jet quenching increase with Gauss-Bonnet coupling and baryon density.

Screening length decreases as baryon density and Gauss-Bonnet coupling increase.

Energy loss of quarks is enhanced by baryon density and angular velocity, but suppressed by Gauss-Bonnet coupling.

Abstract

In this work, holographic approach has been used to analyse the transport properties of baryon rich back-reacted thermal plasma with finite 't Hooft coupling correction. The dual bulk geometry is charged AdS black hole with higher derivative Gauss-Bonnet (GB) correction and string cloud. Specially, we have studied the nature of drag force, jet quenching parameter, screening length, radial profile and energy loss with respect to different parameters. The drag force and jet quenching parameter are enhanced with GB coupling, baryon and flavor density whereas the screening length reduces with these parameters. The radial profile and energy loss of the rotating quark has also been studied and it is observed that the radial profile decreases with increase in baryon potential and flavor density, temperature and angular frequency, whereas it is enhanced with conjugate momenta and GB coupling. Further, the energy loss of the quark grows with potential and flavor density, velocity and angular frequency and it is suppressed with GB coupling.
