“…Recently CLEO came up with the new value for F D * |V cb | = 0.0424 ± 0.0018 stat ± 0.0019 syst [95] which is significantly higher than both their old number and the current LEP average value 0.0345 ± .0007 stat ± 0.0015 syst [96], and now has larger error bars. Taking it literally, one even observes 'overshooting' -the central value for |V cb | under the same theoretical assumptions would be even higher than the result from Γ sl (B).…”

Achievements in the heavy quark theory over the last decade are reviewed, with the main emphasis put on dynamical methods which quantify nonperturbative effects via application of the Operator Product Expansion. These include the total weak decay rates of heavy flavor hadrons and nonperturbative corrections to heavy quark sum rules. Two new exact superconvergent sum rules are derived; they differ from the known ones in that they are finite and normalization point independent in perturbation theory. A new hadronic parameter Σ is introduced which is a spinnonsinglet analogue of Λ = M B −m b ; it is expected to be about 0.25 GeV. The first sum rule implies the bound ρ 2 > 3/4 for the slope of the Isgur-Wise function. The heavy quark potential is discussed and its connection to the infrared contributions in the heavy quark mass. Among applications extraction of |V cb | from the total semileptonic and from the B → D * zero recoil rates is addressed, as well as extracting |V ub | from Γ sl (b → u). Practical aspects of local quark-hadron duality are briefly discussed.
