N2 - We report on the MILC Collaboration’s calculation of fB, fBs, fD, fDs, and their ratios. Our central values come from the quenched approximation, but the quenching error is estimated from NF = 2 dynamical staggered lattices. We use Wilson light valence quarks and Wilson and static heavy quarks. We find, for example, fB = 157 ± 11−9−0+25+23MeV, fBs/fB = 1.11 ± 0.02−0.3+0.04 ± 0.03, fDs = 210 ± 9−9−1+25+17MeV, and fB/fDs = 0.75 ± 0.03−0.02−0.00+0.04+0.08, where the errors are statistical, systematic (within the quenched approximation), and systematic (of quenching), respectively.
