Thermodynamics of N=1 supersymmetric QCD

TL;DR

This paper investigates the thermodynamics of N=1 supersymmetric QCD across different temperature regimes using dual descriptions, perturbation theory, and high-temperature expansions to understand the intermediate temperature behavior.

Contribution

It provides a detailed analysis of the low and high temperature phases of supersymmetric QCD using duality and perturbation methods, exploring the intermediate regime where both approaches overlap.

Findings

Perturbative calculation of pressure in the low-temperature confined phase.

Identification of a potential temperature window where both perturbative expansions are valid.

Insights into the dependence of thermodynamic behavior on scale parameters in dual descriptions.

Abstract

We use the dual description proposed by Seiberg to calculate the pressure in the low temperature confined phase of $N=1$ supersymmetric QCD using perturbation theory to $O(g^3_m)$, where $g_m$ is the gauge coupling in the dual theory. Combining this result with the usual high temperature expansion based on asymptotic freedom, we study how the physics in the intermediate temperature regime depends on the relative size of the scale parameters in the two descriptions. In particular we explore the possibility of having a temperature range where both perturbation expansions are valid.
