We use an appropriate combination of moments of finite energy sum rules in QCD in order to compute the B q -meson decay constants f B and TeX . We perform the calculation using a two-loop computation of the imaginary part of the pseudoscalar two point function in terms of the running bottom quark mass. The results are stable against the so-called QCD duality threshold, and they are in agreement with the estimates obtained from Borel transform QCD sum rules and lattice computations. | |||
