Universality of the Axial Anomaly in Lattice QCD
M. Frewer, H. J. Rothe
We prove that lattice QCD generates the axial anomaly in the continuum limit under very general conditions on the lattice action, which includes the case of Ginsparg-Wilson fermion…
Chiral symmetry restoration and axial vector renormalization for Wilson fermions
T. Reisz, H. J. Rothe
Lattice gauge theories with Wilson fermions break chiral symmetry. In the U(1) axial vector current this manifests itself in the anomaly. On the other hand it is generally expected…
Lattice QED and Universality of the Axial Anomaly
T. Reisz, H. J. Rothe
We give a perturbative proof that U(1) lattice gauge theories generate the axial anomaly in the continuum limit under very general conditions on the lattice Dirac operator. These c…
Renormalization of lattice gauge theories with massless Ginsparg Wilson fermions
T. Reisz, H. J. Rothe
Using functional techniques, we prove, to all orders of perturbation theory, that lattice vector gauge theories with Ginsparg Wilson fermions are renormalizable. For two or more ma…
The axial anomaly in lattice QED. A universal point of view
T. Reisz, H. J. Rothe
We give a perturbative proof that U(1) lattice gauge theories generate the axial anomaly in the continuum limit under very general conditions on the lattice Dirac operator. These c…
A New Look at the Axial Anomaly in Lattice QED with Wilson Fermions
H. J. Rothe, Neda Sadooghi
By carrying out a systematic expansion of Feynman integrals in the lattice spacing, we show that the axial anomaly in the U(1) lattice gauge theory with Wilson fermions, as determi…
Lattice Artefacts In The Non-Abelian Debye Screening Mass In One Loop Order
P. Kaste, H. J. Rothe
We compute the electric screening mass in lattice QCD with Wilson fermions at finite temperature and chemical potential to one-loop order, and show that lattice artefacts arising f…
Continuum Behaviour of Lattice QED, Discretized with One-Sided Lattice Differences, in One-Loop Order
Neda Sadooghi, Heinz J. Rothe
A lattice action for QED is considered, where the derivatives in the Dirac operator are replaced by one-sided lattice differences. A systematic expansion in the lattice spacing of…
Lattice energy sum rules and the trace anomaly
Heinz J. Rothe
We show that the additional contribution to the Michael lattice energy sum rule for the static quark-antiquark potential, pointed out recently, can be identified with the contribut…
A NOVEL LOOK AT THE MICHAEL LATTICE SUM RULES
Heinz J. Rothe
We reconsider the derivation of the Michael lattice sum rules, which relate the energy and action stored in a flux tube of a quark-antiquark pair to the static interquark potential…
