Abstract

We report on a recent computation of theform factors in semi-leptonic decays of the Bsusing Heavy Quark Effective Theory (HQET) formalismapplied on the lattice. The connection of the form factorswith the 2-point and 3-point correlators on the lattice isexplained, and the subsequent non-perturbative renormalizationof HQET and it's matching to Nf=2 QCD is outlined. Theresults of the (static) leading-order calculation in thecontinuum limit is presented.
