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 \ensuremathλ_B=460\ifmmode±\else\textpm\fi110MeV at the scale of 1 GeV. A simple QCD-motivated parametrization of the distribution amplitude is suggested.
