One-Particle Inclusive Semi-Leptonic B decays
C. Balzereit, T. Mannel
Abstract
We propose a method for a QCD based calculation of one-particle inclusive decays of the form B D X or B D* X. It is based on the heavy mass limit and a short distance expansion of the amplitudes, which yield a power series in the parameter 1/M2X for the spectra and in ΛQCD mb/(mb - mc)2 for the rates. We study the leading term of this expansion for the case of the semi--leptonic decays B D X l+ ν.
