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…
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…
The Upsilon Spectrum from Lattice QCD with 2+1 Flavors of Dynamical Quarks
A. Gray, C. Davies, M. Alford +8
We describe the bottomonium spectrum obtained on the MILC configurations which incorporate 2+1 flavors of dynamical quarks. We compare to quenched and 2 flavor results also on MILC…
