Abstract
We report on our effort toward a determination of the heavy-light deca y constant in quenched QCD. Simulation results are analyzed in terms o f the non-relativistic interpretation of relativistic fermions fully i ncorporating one-loop corrections in the mass and current renormalizat ion factors for massive quark. For the Wilson action for which the ana lysis is completed, we obtain f(D)=192(30)MeV, f(Ds)=214(33)MeV, f(B)= 171(29)MeV and f(Bs)=193(32)MeV in the continuum limit.
