Notes on a SQCD-like plasma dual and holographic renormalization

TL;DR

This paper investigates the thermodynamics and jet quenching in a holographic model of a SQCD-like plasma, confirming the validity of holographic renormalization and finding a zero jet quenching parameter consistent with prior results.

Contribution

It provides a detailed analysis of thermodynamics and jet quenching in a backreacted SQCD-like plasma using multiple holographic renormalization methods, validating recent prescriptions.

Findings

Thermodynamics resemble Little String Theory with fixed Hagedorn temperature.

Holographic renormalization methods are consistent and reliable.

Jet quenching parameter is zero in this model.

Abstract

We study the thermodynamics and the jet quenching parameter of a black hole solution dual to a SQCD-like plasma which includes the backreaction of fundamental flavors. The free energy is calculated in several ways, including some recently proposed holographic renormalization prescriptions. The validity of the latter is confirmed by the consistency with the other methods. The resulting thermodynamic properties are similar to the Little String Theory ones: the temperature is fixed at the Hagedorn value and the free energy is vanishing. Finally, an accurate analysis of the relevant string configurations shows that the jet quenching parameter is zero in this model, in agreement with previous findings.
