Matching of lambdaB onto HQET
Abstract
The quantity 1/lambdaB, the inverse moment of the B-meson light-cone wave function, plays an important role in exclusive B-decays. I calculate the matching coefficient of lambdaB defined in QCD onto lambdaB defined in HQET. This is useful for comparing results that have been obtained in QCD to results obtained in HQET.
