PROGRESS IN FOUR-DIMENSIONAL LATTICE SUPERSYMMETRY
- Physics
- 2009
We are entering an era where a number of large-scale lattice simulations of four-dimensional supersymmetric theories are under way. Moreover, proposals for how to approach such studies continue to…
Rooted staggered fermions: good, bad or ugly?
- Physics
- 2006
I give a status report on the validity of the so-called “fourt h-root trick”, i.e. the procedure of representing the determinant for a single fermion by the fourth root of the staggered fermion…
Light Hadron Masses from Lattice QCD
- Physics
- 2012
This article reviews lattice QCD results for the light hadron spectrum. An overview of different formulations of lattice QCD with discussions on the fermion doubling problem and improvement programs…
Logarithmic corrections to O($a$) and O($a^2$) effects in lattice QCD with Wilson or Ginsparg-Wilson quarks

Lattice gauge theory with staggered fermions: how, where, and why (not)
- Physics
- 2007
Many results from lattice QCD of broad importance to particle and nuclear physics are obtained with 2+1 flavors of staggered sea quarks. In the continuum limit, staggered fermions yield four species,…

Power Counting and Renormalization in Lattice Field Theory
- Physics
- 1988
In an Euclidean quantum field theory a space-time lattice provides a quite natural non-perturbative ultraviolet cutoff. This has lead to a variety of non-perturbative methods. Observable physics has…
The Dirac-Kähler equation and fermions on the lattice
- Physics
- 1982
The geometrical description of spinor fields by E. Kähler is used to formulate a consistent lattice approximation of fermions. The relation to free simple Dirac fields as well as to Susskind's…

A power counting theorem for Feynman integrals on the lattice
- Mathematics
- 1988
A convergence theorem is proved, which states sufficient conditions for the existence of the continuum limit for a wide class of Feynman integrals on a space-time lattice. A new kind of a…
A convergence theorem for lattice Feynman integrals with massless propagators
- Physics, Mathematics
- 1988
It is shown that for non-vanishing lattice spacing, conventional infrared power counting conditions are sufficient for convergence of lattice Feynman integrals with zero-mass propagators. If these…
