Leptonic decays of D-wave vector quarkonia
A. Krassnigg, M. Gomez-Rocha, T. Hilger
We give a short and basic introduction to our covariant Dyson-Schwinger-Bethe-Salpeter-equation approach using a rainbow-ladder truncated model of QCD, in which we investigate the…
Effects of a dressed quark-gluon vertex in pseudoscalar heavy-light mesons
M. Gomez-Rocha, T. Hilger, A. Krassnigg
Using a simple model in the context of the Dyson-Schwinger-Bethe-Salpeter approach, we investigate the effects of a dressed-quark-gluon vertex on pseudoscalar meson masses. In part…
Baryons in and beyond the quark-diquark model
G. Eichmann, R. Alkofer, C. S. Fischer +2
We examine the nucleon's electromagnetic form factors in a Poincare-covariant Faddeev framework. The three-quark core contributions to the form factors are obtained by employing a…
Rho-meson, Bethe-Salpeter equation, and the far infrared
Martina Blank, A. Krassnigg, Axel Maas
The Bethe-Salpeter equation in QCD connects the gauge-dependent gluon and quark degrees of freedom with the gauge-invariant properties of mesons. We study the rho meson mass and de…
The QCD chiral transition temperature in a Dyson-Schwinger-equation context
M. Blank, A. Krassnigg
We analyze the chiral phase transition with the help of the QCD gap equation. Various models for the effective interaction in rainbow truncation are contrasted with regard to the r…
Survey of J=0,1 mesons in a Bethe-Salpeter approach
A. Krassnigg
The Bethe-Salpeter equation is used to comprehensively study mesons with J=0,1 and equal-mass constituents for quark masses from the chiral limit to the b-quark mass. The survey co…
