QCD Sum Rules for Heavy Flavour Physics

Abstract

Uses of QCD sum rules for heavy flavoured hadrons are discussed. "Standard" applications such as the determination of the $b$, $c$ quark masses, the calculation of $f_B$, $f_D$ and of the heavy-to-light form factors are overviewed. Furthermore, a new approach to calculate the $B\to \pi \pi$ hadronic matrix elements from QCD light-cone sum rules is described.
