Aspects of model dependence of eta'-eta complex treated by going beyond the isospin limit
Davor Horvatic, Dubravko Klabucar, Dalibor Kekez
Exploring the extent of model dependence, we study effects of certain Ansaetze for the T-dependence of the correction term in the QCD topological susceptibility. The one producing…
Temperature Dependence of the Axion Mass in a Scenario Where the Restoration of Chiral Symmetry Drives the Restoration of the Symmetry
Davor Horvatić, Dalibor Kekez, Dubravko Klabučar
The temperature () dependence of the axion mass is predicted for 's up to the chiral restoration temperature of QCD. The axion is related to the an…
Medium induced Lorentz symmetry breaking effects in nonlocal PNJL models
S. Benic, D. Blaschke, G. A. Contrera +1
In this paper we detail the thermodynamics of two flavor nonlocal Polyakov-Nambu-Jona-Lasinio models for different parametrizations of the quark interaction regulators. The structu…
Restoration of singlet axial symmetry at finite temperature
S. Benic, D. Horvatic, D. Kekez +1
To accomodate recent RHIC data on eta prime multiplicity, we propose a minimal modification of the Witten-Veneziano relation at high temperature. This renders a significant drop of…
Width of the QCD transition in a Polyakov-loop DSE model
D. Horvatic, D. Blaschke, D. Klabucar +1
We consider the pseudocritical temperatures for the chiral and deconfinement transitions within a Polyakov-loop Dyson-Schwinger equation approach which employs a nonlocal rank-2 se…
Unexpectedly small empirical vector strangeness of nucleons realized in a baryon model
D. Horvatic, D. Klabucar, D. Mekterovic
Most of model considerations of the hidden nucleon strangeness, as well as some preliminary experimental evidence, led to the expectations of relatively sizeable strange vector for…
