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…
A Dyson-Schwinger model beyond isospin limit prepared for investigating U_A(1)-breaking temperature dependence
Davor Horvatić, Dalibor Kekez, Dubravko Klabučar
Motivated by our earlier findings of sensitive quark-flavor dependence of QCD topological susceptibility on products of current quark masses and corresponding condensates, we allow…
Pion observables calculated in Minkowski and Euclidean spaces with Ansätze for quark propagators
Dalibor Kekez, Dubravko Klabučar
We study two quark--propagator meromorphic Ansätze that admit clear connection between calculations in Euclidean space and Minkowski spacetime. The connection is established throug…
T-dependence of the axion mass when the U_A(1) and chiral symmetry breaking are tied
Dubravko Klabučar, Davor Horvatić, Dalibor Kekez
Modulo the scale of spontaneous breaking of Peccei-Quinn symmetry, the axion mass is given by the QCD topological susceptibility at all temperatures . From an ap…
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…
and mesons at high T when the U_A(1) and chiral symmetry breaking are tied
Davor Horvatić, Dalibor Kekez, Dubravko Klabučar
The approach to the eta'-eta complex employing chirally well-behaved quark-antiquark bound states and incorporating the non-Abelian axial anomaly of QCD through the generalization…
