Abstract

We review a lattice strategy how to non-perturbatively determine the\ncoefficients in the HQET expansion of all components of the heavy-light axial\nand vector currents, including 1/m_h-corrections. We also discuss recent\npreliminary results on the form factors parameterizing semi-leptonic B-decays\nat the leading order in 1/m_h.\n
