Heavy quark distribution function in QCD and the $AC^{2}M^{2}$ model
We show that the phenomenological \ACM ansatz is consistent with QCD through order $1/m_b$ in the description of $B\ra l\bar \nu_l+X_u$ and $B\ra \gamma +X_s$ transitions, including their energy spectra and differential distributions. This suggests a concrete realization for the QCD distribution fun...
