Lattice Gauge Theory
Hartmut Wittig
The status of lattice calculations in Quantum Field Theory is reviewed. A major part is devoted to recent progress in formulating exact chiral symmetry on the lattice. Another topi…
Scaling tests of the improved Kogut-Susskind quark action
The MILC collaboration, C. Bernard, T. Burch +8
Improved lattice actions for Kogut-Susskind quarks have been shown to improve rotational symmetry and flavor symmetry. In this work we find improved scaling behavior of the rho and…
Potts Flux Tube Model at Nonzero Chemical Potential
Jac Condella, Carleton DeTar
We model the deconfinement phase transition in quantum chromodynamics at nonzero baryon number density and large quark mass by extending the flux tube model (three-state, three-dim…
Scaling and Eigenmode Tests of the Improved Fat Clover Action
Mark Stephenson, Carleton DeTar, Thomas DeGrand +1
We test a recently proposed improved lattice-fermion action, the fat link clover action, examining indicators of pathological small-quark-mass lattice artifacts ("exceptional confi…
Heavy-Light Decay Constants with Dynamical Gauge Configurations and Wilson or Improved Valence Quark Action
MILC Collaboration, Claude Bernard, Thomas DeGrand +8
We describe a calculation of heavy-light decay constants including virtual quark loop effects. We have generated dynamical gauge configurations at three values using two flavor…
First Signs for String Breaking in Two-Flavor QCD
Carleton DeTar, Urs Heller, Pierre Lacock
We have been examining the phenomenon of string breaking in QCD with two flavors of dynamical staggered quarks. We construct a transfer matrix from a combination of ``string'' and…
