DESCRIPTION:Matthew Wingate\, University of Washington\n\n Lattice QCD calc
ulations now include the effects of 2 light sea quarks and 1 strange sea q
uark through the use of an improved staggered fermion action\; consequentl
y\, calculations important to quark flavor physics are free of the unsyste
matic errors that infected previous calculations. Furthermore\, the work
of the previous decade to reduce discretization errors\, to tame lattice p
erturbation theory\, to control light quark mass extrapolations\, and to i
mplement\nheavy lattice quarks is finally converging to yield realistic\,
accurate calculations. In this talk I discuss some important recent innova
tions we employ\, show tests of the methodology\, and present our current
results. I conclude by showing the impact of the results on constraints o
f Standard Model parameters and by mapping the route for further improveme
nt.\n
