Description
We report on a recent computation of the form factors in semi-leptonic decays of the $B_s$ using Heavy Quark Effective Theory (HQET) formalism applied on the lattice. The connection of the form factors with the 2-point and 3-point correlators on the lattice is explained, and the subsequent non-perturbative renormalization of HQET and it's matching to $N_f=2$ QCD is outlined. The results of the (static) leading-order calculation in the continuum limit is presented. Preliminary results on extending the leading-order computation by including the $1/m$ effects (where m is the heavy-quark mass) are mentioned.
