Full text not available from this repository.Abstract
The B-meson distribution amplitude is calculated using QCD sum rules. In particular we obtain an estimate for the integral relevant to exclusive B decays lambda(B)=460+/-110 MeV at the scale of 1 GeV. A simple QCD-motivated parametrization of the distribution amplitude is suggested.
