The width of the decay anti B0→π+e-anti νe in QCD
Description
The formfactor of the decay anti B0→π+e-anti νe is found in the physical region of the transverse momentum squared by means of the QCD sum rule method. The full width of the decay is estimated. The results can serve as a basis for the determination of the Kobayashi-Maskawa matrix element for the b→u transition. (orig.)
