Abstract

We describe the current status of the MILC collaboration computation of f_B, f_Bs, f_D, f_Ds, and their ratios. Progress over the past year includes: better statistics and plateaus at β = 6.52 (quenched), β = 5.6 (N_F = 2) and β = 5.445 (N_F = 2), new runs with a wide range of dynamical quark masses at β = 5.5 (N_F = 2), an estimate of the systematic errors due to the chiral extrapolation, and an improved analysis which consistently takes into account both the correlations in the data at every stage and the systematic effects due to changing fitting ranges.
