B and D Meson Decay Constants
Abstract
We present an update of our calculations of the decay constants of the D, Ds, B, and Bs mesons in unquenched 2+1 flavor QCD. We use the MILC library of improved staggered gauge ensembles at lattice spacings 0.09, 0.12, and 0.15 fm, clover heavy quarks with the Fermilab normalizations, and improved staggered light valence quarks.
