Chiral symmetry breaking via constituent quarks for qbarq pseudoscalar mesons
D. Kekez, D. Klabucar, M. D. Scadron
We base our chiral symmetry approach on the quark-level linear sigma model Lagrangian. Then we review the Nambu--Goldstone theorem with vanishing pi, K, eta_8 masses. Next we dynam…
A Bethe-Salpeter study with the <A^2>-enhanced effective QCD coupling
Dalibor Kekez, Dubravko Klabucar
Dyson-Schwinger equations provide a prominent approach to physics of strong interactions. To reproduce the hadronic phenomenology well, the Dyson-Schwinger approach in the rainbow-…
Circumventing the axial anomalies and the strong CP problem
D. Kekez, D. Klabucar, M. D. Scadron
Many meson processes are related to the U_A(1) axial anomaly, present in the Feynman graphs where fermion loops connect axial vertices with vector vertices. However, the coupling o…
Schwinger-Dyson approach to light pseudoscalars
Dubravko Klabucar, Dalibor Kekez
We review briefly some of the successes of Schwinger-Dyson (SD) approach to the physics of quarks and hadrons, primarily light pseudoscalar mesons including eta and eta'. The main…
Phenomenological Schwinger-Dyson approach to eta-eta' mass matrix
Dalibor Kekez, Dubravko Klabucar
It is reviewed pedagogically how a very successful description of the eta-eta' mass matrix can be achieved in the consistently coupled Schwinger-Dyson and Bethe-Salpeter approach i…
On the eta-eta' complex in the SD-BS approach
Dubravko Klabucar, Dalibor Kekez, Michael D. Scadron
The bound-state Schwinger-Dyson and Bethe-Salpeter (SD-BS) approach is chirally well-behaved and provides a reliable treatment of the eta-eta' complex although a ladder approximati…
