The vacuum nature of the QCD condensates
H. Reinhardt, H. Weigel
Recently it was claimed that QCD condensates were associated with the internal dynamics of the hadrons. We challenge this "in-hadron" picture of the QCD condensates and show that i…
The Elusiveness of Infrared Critical Exponents in Landau Gauge Yang--Mills Theories
C. S. Fischer, R. Alkofer, H. Reinhardt
We solve a truncated system of coupled Dyson-Schwinger equations for the gluon and ghost propagators in SU() Yang-Mills theories in Faddeev-Popov quantization on a four-torus.…
Gluon propagators and quark confinement
K. Langfeld, H. Reinhardt, J. Gattnar
The gluon propagator is investigated in Landau and in maximal center gauge for the gauge group SU(2) by means of lattice gauge simulations. We find that Gribov ambiguities arising…
Nucleon Form Factors in the Covariant Diquark-Quark Model
R. Alkofer, M. Oettel
The nucleon is described as a bound state of a quark and an extended diquark. Hereby the notion ``diquark'' refers to the modelling of separable correlations in the two-quark Green…
Production Processes as a Tool to Study Parameterizations of Quark Confinement
S. Ahlig, R. Alkofer, C. Fischer +3
We introduce diquarks as separable correlations in the two-quark Green's function to facilitate the description of baryons as relativistic three-quark bound states. These states th…
Octet and Decuplet Baryons in a Confining and Covariant Diquark-Quark Model
R. Alkofer, S. Ahlig, C. Fischer +2
We treat baryons as bound states of scalar or axialvector diquarks and a constituent quark which interact through quark exchange. We obtain fully four-dimensional wave functions fo…
