How reliable are the HQET-sum rule predictions?
We test the internal consistencies and the reliability of the existing estimates of the decay constant f_B in the static limit, the meson-quark mass gap \bar \Lambda and the kinetic energy K of a heavy quark obtained from the heavy quark effective theory (HQET)-sum rules. Finite energy local duality...
