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…
