Heavy Quarks from QCD Spectral Sum Rules
Abstract
Description
This is a short review of the present status of the dynamics of the heavy quarks extracted from QCD spectral sum rules. We discuss the determination of the ``perturbative" quark mass, the decay constants of the $D$ and $B$ mesons, the form factors of the semileptonic and radiative decays of the $B$ mesons, the slope of the Isgur--Wise function and the emerged value of $V_{cb}$. We mention shortly some properties of the hybrid and $B_c$ mesons.
