Matching of lambda_B onto HQET
Abstract
Description
The quantity 1/lambda_B, 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 lambda_B defined in QCD onto lambda_B defined in HQET. This is useful for comparing results that have been obtained in QCD to results obtained in HQET.
