Heavy-light mesons with staggered light quarks
Matthew Wingate, Junko Shigemitsu, Christine T. H. Davies +2
We demonstrate the viability of improved staggered light quarks in studies of heavy-light systems. Our method for constructing heavy-light operators exploits the close relation bet…
Taste-Changing in Staggered Quarks
Quentin Mason, Peter Lepage, Paul Mackenzie +4
We present results from a systematic perturbative investigation of taste-changing in improved staggered quarks. We show one-loop taste-changing interactions can be removed perturba…
The determination of alpha_s from lattice QCD with 2+1 flavors of dynamical quarks
C. Davies, A. Gray, M. Alford +8
We describe the first lattice determination of the strong coupling constant with 3 flavors of dynamical quarks. The method follows previous analyses in using a perturbative expansi…
B_s Mesons using Staggered Light Quarks
Matthew Wingate, Junko Shigemitsu, G. Peter Lepage +2
Last year we proposed using staggered fermions as the light quarks, combined with nonrelativistic heavy quarks, in simulations of heavy-light mesons. A first round of tests which f…
On the strange quark mass with improved staggered quarks
J. Hein, C. Davies, G. P. Lepage +2
We present results on the sum of the masses of light and strange quark using improved staggered quarks. Our calculation uses 2+1 flavours of dynamical quarks. The effects of the dy…
Static Potential and Local Color Fields in Unquenched Three-Dimensional Lattice QCD
Howard D. Trottier, Kit Yan Wong
String breaking by dynamical quarks in (2+1)-d lattice QCD is demonstrated in this project, by measuring the static potential and the local color-electric field strength between a…
