The quark propagator in QCD and QCD
Romain Contant, Markus Q. Huber
QCD-like theories provide testing grounds for truncations of functional equations at non-zero density, since comparisons with lattice results are possible due to the absence of the…
Influence of broken flavor and C and P symmetry on the quark propagator
Axel Maas, Walid Ahmed Mian
Embedding QCD into the standard model breaks various symmetries of QCD explicitly, especially C and P. While these effects are usually perturbatively small, they can be amplified i…
An exploratory study of Yang-Mills three-point functions at non-zero temperature
Markus Q. Huber
Results for three-point functions of Landau gauge Yang-Mills theory at non-vanishing temperature are presented and compared to lattice results. It is found that the three-gluon ver…
Three-point vertex functions in Yang-Mills Theory and QCD in Landau gauge
Adrian L. Blum, Reinhard Alkofer, Markus Q. Huber +1
Solutions for the three-gluon and quark-gluon vertices from Dyson-Schwinger equations and the three-particle irreducible formalism are discussed. Dynamical quarks (``unquenching'')…
Charming quasi-exotic open-flavor mesons
Thomas Hilger, Andreas Krassnigg
We discuss charmed mesons in the covariant Dyson-Schwinger-Bethe-Salpeter-equation approach. In particular we computed masses, leptonic decay constants, and an orbital-angular-mome…
Quark Propagator with electroweak interactions in the Dyson-Schwinger approach
Walid Ahmed Mian, Axel Maas
Motivated by the non-negligible dynamical backcoupling of the electroweak interactions with the strong interaction during neutron star mergers, we study the effects of the explicit…
Baryons as relativistic three-quark bound states
Gernot Eichmann, Helios Sanchis-Alepuz, Richard Williams +2
We review the spectrum and electromagnetic properties of baryons described as relativistic three-quark bound states within QCD. The composite nature of baryons results in a rich ex…
On light baryons and their excitations
Gernot Eichmann, Christian S. Fischer, Helios Sanchis-Alepuz
We study ground states and excitations of light octet and decuplet baryons within the framework of Dyson-Schwinger and Faddeev equations. We improve upon similar approaches by expl…
Quasi-exotic open-flavor mesons
T. Hilger, A. Krassnigg
Meson states with exotic quantum numbers arise naturally in a covariant bound-state framework in QCD. We investigate the consequences of shifting quark masses such that the states…
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 vector heavy-light mesons and theory average of B(c)* meson mass
M. Gomez-Rocha, T. Hilger, A. Krassnigg
We extend earlier investigations of heavy-light pseudoscalar mesons to the vector case, using a simple model in the context of the Dyson-Schwinger-Bethe-Salpeter approach. We inves…
Gauge invariance and the physical spectrum in the two-Higgs-doublet model
Axel Maas, Leonardo Pedro
Observable states are gauge-invariant. In a non-Abelian gauge theory, these are necessarily composite operators. We investigate the spectrum of these operators in the two-Higgs-dou…
