TL;DR
This paper investigates the Mott effect for pions and kaons using the Beth-Uhlenbeck approach within the PNJL model, analyzing their thermodynamic contributions through phase shifts and comparing results with lattice QCD data.
Contribution
It introduces a novel application of the Beth-Uhlenbeck approach to pions and kaons in the PNJL model, linking phase shifts to thermodynamics and validating with lattice QCD results.
Findings
Phase shifts effectively encode thermodynamic contributions.
The model reproduces lattice QCD thermodynamics for pions and kaons.
Temperature dependence of phase shifts reveals Mott transition behavior.
Abstract
In the present work the Mott effect for pions and kaons is described within a Beth- Uhlenbeck approach on the basis of the PNJL model. The contribution of these degrees of freedom to the thermodynamics is encoded in the temperature dependence of their phase shifts. A comparison with results from lattice QCD thermodynamics is performed.
