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