Strategy and tree-level study %A Michele Della Morte %A Samantha Dooling %A Jochen Heitger %A Dirk Hesse %A Hubert Simma %J Physics %D 2013 %I arXiv %X We present a strategy how to match the full set of components of the heavy-light axial and vector currents in Heavy Quark Effective Theory (HQET), up to and including 1/m-corrections, to QCD. While the ultimate goal is to apply these matching conditions non-perturbatively, in this study we first have implemented them at tree-level, in order to find good choices of the matching observables with small O(1/m^2) contributions. They can later be employed in the non-perturbative matching procedure which is a crucial part of precision HQET computations of semileptonic decay form factors in lattice QCD. %U http://arxiv.org/abs/1312.1566v2
