Lattice Gauge Actions for Fixed Topology
XLF Collaboration, W. Bietenholz, K. Jansen +4
We test a set of lattice gauge actions for QCD that suppress small plaquette values and in this way also suppress transitions between topological sectors. This is well suited for s…
Light hadron spectra and wave functions in quenched QCD with overlap quarks on a large lattice
Federico Berruto, Nicolas Garron, Christian Hoelbling +5
A simulation of quenched QCD with the overlap Dirac operator has been completed using 100 Wilson gauge configurations at beta=6 on an 18^3x64 lattice. We present results for meson…
Electroweak penguins and SUSY K^0-\bar K^0 mixing with Neuberger quarks
Federico Berruto, Nicolas Garron, Christian Hoelbling +5
We present results for Delta I=3/2 and Delta S=2 matrix elements relevant for CP violation in K->Pi Pi decays and for the K_S-K_L mass difference in the standard model and beyond.…
Testing a Topology Conserving Gauge Action in QCD
S. Shcheredin, W. Bietenholz, K. Jansen +3
We study lattice QCD with a gauge action, which suppresses small plaquette values. Thus the MC history is confined to a single topological sector over a significant time, while oth…
Lattice artefacts in SU(3) lattice gauge theory with a mixed fundamental and adjoint plaquette action
Martin Hasenbusch, Silvia Necco
We investigated SU(3) lattice gauge theory with a fundamental and adjoint plaquette term in the action. The purpose is to test whether the choice of a negative adjoint coupling can…
SU(3) lattice gauge theory with a mixed fundamental and adjoint plaquette action: Lattice artefacts
M. Hasenbusch, S. Necco
We study the four-dimensional SU(3) gauge model with a fundamental and an adjoint plaquette term in the action. We investigate whether corrections to scaling can be reduced by usin…
