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 Nf = 2 + 1 lattice QCD thermodynamics is performed.
Highlights
One of the central problems in the investigation of the transition from hadronic to quark matter is a microphysical description of the dissociation of hadrons into their quark constituents
Since an ab-initio description of QCD thermodynamics within simulations of lattice QCD (LQCD) is yet limited to finite temperatures and low chemical potentials only, the development of effective model descriptions is of importance
We report here results for the case of vanishing chemical potentials
Summary
One of the central problems in the investigation of the transition from hadronic to quark matter is a microphysical description of the dissociation of hadrons into their quark constituents. Since an ab-initio description of QCD thermodynamics within simulations of lattice QCD (LQCD) is yet limited to finite temperatures and low chemical potentials only, the development of effective model descriptions is of importance.
