Preliminary heavy-light decay constants from the MILC collaboration

Preliminary results from the MILC collaboration for \(f_B\), \(f_{B_s}\), \(f_D\), \(f_{D_s}\) and their ratios are presented. We compute in the quenched approximation at \(\beta=6.3\), 6.0 and 5.7 with Wilson light quarks and static and Wilson heavy quarks. We attempt to quantify systematic errors...

Description
Summary:Preliminary results from the MILC collaboration for \(f_B\), \(f_{B_s}\), \(f_D\), \(f_{D_s}\) and their ratios are presented. We compute in the quenched approximation at \(\beta=6.3\), 6.0 and 5.7 with Wilson light quarks and static and Wilson heavy quarks. We attempt to quantify systematic errors due to finite volume, finite lattice spacing, large \(am\), and fitting and extrapolation uncertainties. The hopping parameter approach of Henty and Kenway is used to treat the heavy quarks; the sources are Coulomb gauge gaussians.
