Non-perturbative renormalization of quark bilinear operators and B_K using domain wall fermions
Y. Aoki, P. A. Boyle, N. H. Christ +11
We present a calculation of the renormalization coefficients of the quark bilinear operators and the K-Kbar mixing parameter B_K. The coefficients relating the bare lattice operato…
The Static Approximation to B Meson Mixing using Light Domain-Wall Fermions: Perturbative Renormalization and Ground State Degeneracies
Norman H. Christ, Thomas T. Dumitrescu, Taku Izubuchi +1
We discuss the theoretical input into the current RBC-UKQCD calculation of and using a smeared static heavy quark propagator, light domain-wall quarks…
The QCD Equation of State with almost Physical Quark Masses
M. Cheng, N. H. Christ, S. Datta +12
We present results on the equation of state in QCD with two light quark flavors and a heavier strange quark. Calculations with improved staggered fermions have been performed on la…
Localization and chiral symmetry in 2+1 flavor domain wall QCD
David J. Antonio, Kenneth C. Bowler, Peter A. Boyle +15
We present results for the dependence of the residual mass of domain wall fermions (DWF) on the size of the fifth dimension and its relation to the density and localization propert…
Neutral kaon mixing from 2+1 flavor Domain Wall QCD
D. J. Antonio, P. A. Boyle, T. Blum +16
We present the first results for neutral kaon mixing using 2+1 flavors of domain wall fermions. A new approach is used to extrapolate to the physical up and down quark masses from…
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…
