We report on a two-flavor lattice QCD estimate of the and leptonic decays parameterized by the decay constants and . In addition to their relevance for phenomenology, their extraction has allowed us to investigate whether the “step scaling in mass” strategy is suitable with Wilson–Clover fermions to smoothly extrapolate quantities of the heavy-strange sector up to the bottom scale. From the central value of quoted by FLAG at and our ratio , we obtain MeV and .
