Gauge transformations in non-perturbative chiral gauge theories
Werner Kerler
We reconsider gauge-transformation properties in chiral gauge theories on the lattice observing all pertinent information and show that these properties are actually determined in…
Gauge transformations in lattice chiral theories
Werner Kerler
We show that gauge-transformation properties of correlation functions in chiral gauge theories on the finite lattice are determined in a general way.
Lattice formulation of chiral gauge theories
Werner Kerler
We present a general formulation of chiral gauge theories, which admits Dirac operators with more general spectra, reveals considerably more possibilities for the structure of the…
Parallel tempering and decorrelation of topological charge in full QCD
E. -M. Ilgenfritz, W. Kerler, M. Müller-Preussker +1
The improvement of simulations of QCD with dynamical Wilson fermions by combining the Hybrid Monte Carlo algorithm with parallel tempering is studied on and lattices.…
Dirac operator normality and chiral properties on the lattice
Werner Kerler
Normality in connection with -hermiticity determines the basic chiral properties and rules. The Ginsparg-Wilson (GW) relation is one of the allowed constraints on the spectrum…
