E. Ruiz Arriola, L.L. Salcedo, E. Megias
TL;DR
This paper investigates how QCD observables transition from hadronic descriptions at low temperatures to quark-gluon descriptions at higher temperatures, focusing on the microscopic basis of the hadron resonance gas model.
Contribution
It provides a microscopic derivation of the hadron resonance gas and explores quark-hadron duality at finite temperature.
Findings
Confirmation of hadron resonance gas validity at low temperatures
Insights into the microscopic origin of quark-hadron duality
Analysis of the Polyakov loop in various representations
Abstract
At low temperatures we expect that all QCD observables are defined in terms of hadrons. This includes the partition function as well as the Polyakov loop in all representations. We analyze the physics underlying a microscopic derivation of the hadron resonance gas.
