Real poles with opposite-sign residues in the non-perturbative quark propagator
R. Alkofer, M. N. Ferreira, A. S. Miramontes +2
We investigate the analytic structure of the quark propagator in the Landau gauge by dynamically coupling the standard gap equation to the non-perturbative quark-gluon vertex. Empl…
No planar degeneracy for the Landau gauge quark-gluon vertex
Georg Wieland, Reinhard Alkofer
Based on a suitable basis system for the quark-gluon vertex' transverse tensor structures and on carefully chosen kinematical variables, the transverse part of the quark-gluon vert…
Timelike form factor for the anomalous process
Angel S. Miramontes, Gernot Eichmann, Reinhard Alkofer
The form factor for the anomalous process is calculated in the isospin limit for several values of the light current-quark mass (i.e., the…
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…
Covariant solution of the three-quark problem in quantum field theory: the nucleon
G. Eichmann, R. Alkofer, A. Krassnigg +1
We provide details on a recent solution of the nucleon's covariant Faddeev equation in an explicit three-quark approach. The full Poincare-covariant structure of the three-quark am…
Faddeev equations: a view of baryon properties
D. Nicmorus, G. Eichmann, A. Krassnigg +1
We present a calculation of the three-quark core contribution to the mass of the Delta-baryon in a Poincare-covariant Faddeev framework. A consistent setup for the dressed-quark pr…
