We report our calculation of the heavy-light decay constants fB and fD on a 203 x 48 lattice at 0 = 5.2 with nf = 2 sea quarks by the fully O(a)-improved Wilson fermion and heavy quarks in Fermilab formalism. We find that the B meson decay constants are consistent with those obtained with the NRQCD
We test the one-loop chiral perturbation theory formula on unquenched lattice data of pseudoscalar meson decay constants. The chiral extrapolation including the effect of the chiral logarithm is attempted and its uncertainty is discussed.
