The results for heavy-light mesons are summarized in Table 1. The results presented here are based on the same statistical sample, consisting of 102 quenched configurations at β = 6.0 with lattice size 16 × 48, as used in our study of fB and fBs [1]. The details of the NRQCD action, the evolution equation for calculating the heavy quark propagator, the method used for setting the lattice scale,...
