Flavor symmetry breaking and scaling for improved staggered actions in quenched QCD
M. Cheng, N. H. Christ, C. Jung +4
We present a study of the flavor symmetry breaking in the pion spectrum for various improved staggered fermion actions. To study the effects of link fattening and tadpole improveme…
First results from 2+1-Flavor Domain Wall QCD: Mass Spectrum, Topology Change and Chiral Symmetry with
D. J. Antonio, T. Blum, K. C. Bowler +23
We present results for the static interquark potential, light meson and baryon masses, and light pseudoscalar meson decay constants obtained from simulations of domain wall QCD wit…
Perturbative renormalization for static and domain-wall bilinears and four-fermion operators with improved gauge actions
Oleg Loktik, Taku Izubuchi
We calculate one-loop renormalization factors for heavy-light bilinears as well as four-fermion operators relevant for mixing calculations on the lattice. We…
Current Physics Results from Staggered Chiral Perturbation Theory
C. Aubin
We review several results that have been obtained using lattice QCD with the staggered quark formulation. Our focus is on the quantities that have been calculated numerically with…
Study of the finite temperature transition in 3-flavor QCD using the R and RHMC algorithms
M. Cheng, N. H. Christ, M. A. Clark +12
We study the finite temperature transition in QCD with three flavors of equal masses using the R and RHMC algorithm on lattices with temporal extent N_τ=4 and 6. For the transition…
The transition temperature in QCD
M. Cheng, N. H. Christ, S. Datta +11
We present a detailed calculation of the transition temperature in QCD with two light and one heavier (strange) quark mass on lattices with temporal extent N_t =4 and 6. Calculatio…
