Onium Masses with Three Flavors of Dynamical Quarks
Steven Gottlieb, L. Levkova, M. DiPierro +5
We have greatly extended an earlier calculation of the charmonium spectrum on three flavor dynamical quark ensembles by using more recent ensembles generated by the MILC collaborat…
More evidence of localization in the low-lying Dirac spectrum
C. Bernard, Ph. de Forcrand, Steven Gottlieb +8
We have extended our computation of the inverse participation ratio of low-lying (asqtad) Dirac eigenvectors in quenched SU(3). The scaling dimension of the confining manifold is c…
Predictions from Lattice QCD
Andreas S. Kronfeld, I. F. Allison, C. Aubin +24
In the past year, we calculated with lattice QCD three quantities that were unknown or poorly known. They are the dependence of the form factor in semileptonic dec…
The locality of the fourth root of staggered fermion determinant in the interacting case
C. Bernard, C. DeTar, Steven Gottlieb +7
The fourth root approximation in LQCD simulations with dynamical staggered fermions requires justification. We test its validity numerically in the interacting theory in a renormal…
Update on pi and K Physics
MILC Collaboration, C. Bernard, C. DeTar +9
We present an update of the MILC studies of the physics of light pseudoscalars using improved staggered fermions. New runs at lighter quark mass, as well as increased statistics fo…
The Equation of State for QCD with 2+1 Flavors of Quarks
C. Bernard, T. Burch, C. DeTar +8
We report results for the interaction measure, pressure and energy density for nonzero temperature QCD with 2+1 flavors of improved staggered quarks. In our simulations we use a Sy…
