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 $γ^\ast Ï\rightarrow ÏÏ$
Angel S. Miramontes, Gernot Eichmann, Reinhard Alkofer
The form factor for the anomalous process $γ^\ast Ï\rightarrow ÏÏ$ is calculated in the isospin limit for several values of the light current-quark mass (i.e.,…
