The Schwinger Model with Perfect Staggered Fermions
W. Bietenholz, H. Dilger
We construct and test a quasi-perfect lattice action for staggered fermions. The construction starts from free fermions, where we suggest a new blocking scheme, which leads to exce…
Comparison of Lambda and Sigma(0) Threshold Production in Proton-Proton Collisions
S. Sewerin, G. Schepers, J. T. Balewski +27
Threshold measurements of the associated strangeness production reactions pp --> p K(+) Lambda and pp --> p K(+) Sigma(0) are presented. Although slight differences in the shapes o…
Evidence for discrete chiral symmetry breaking in N=1 supersymmetric Yang-Mills theory
R. Kirchner, S. Luckmann, I. Montvay +2
In a numerical Monte Carlo simulation of SU(2) Yang-Mills theory with dynamical gauginos we find evidence for two degenerate ground states at the supersymmetry point corresponding…
On the phase diagram of the discrete spin models
Patrick Dorey, Paolo Provero, Roberto Tateo +1
We point out some problems with the previously-proposed phase diagram of the spin models. Consideration of the diagram near to the decoupling surface using both exact and app…
Analysis and Geometry of Boundary-Manifolds of Bounded Geometry
Thomas Schick
In this paper, we investigate analytical and geometric properties of certain non-compact boundary-manifolds, namely manifolds of bounded geometry. One result are strong Bochner typ…
The Schwinger Model with Perfect Staggered Fermions
W. Bietenholz, H. Dilger
We construct a new perfect action for free staggered fermions, which is more local than the one obtained from the standard block average scheme. This pays off in superior propertie…
