Abstract

We present new results for fB+ and fD+ from the MILC 2 + 1 flavor a = 0.09fm "fine" lattice. We use clover heavy quarks in the Fermilab interpretation and improved staggered light quarks. Lattice results from partially quenched QCD fix the parameters of staggered chiral perturbation theory which is used in the extrapolation to the physical decay constants.
