Abstract
We calculate the two-loop QCD correction to the form factors of on-shell b-quark decay to an energetic massless quark, which constitutes the last missing piece required for an View the MathML source determination of |Vub| from inclusive semi-leptonic View the MathML source decays in the shape-function region.
