fBstat and μπ2 in the quasiclassical approximation of sum rules

In the framework of sum rules with the use of the quarkonium mass spectrum, evaluated in the quasiclassical approximation, estimates are obtained for the leptonic constant fBstat ∼- 320 ± 60 MeV in the static limit and for the average heavy quark momentum squared μπ2 ∼- 0.5 ± 0.1 GeV2.
