@article{Harada2001ApplicationOH, title={Application of heavy-quark effective theory to lattice QCD. II. Radiative corrections to heavy-light currents}, author={Junpei Harada and Shoji Hashimoto and Andreas S. Kronfeld and Tetsuya Onogi}, journal={Physical Review D}, year={2001}, volume={65}, pages={094513-1-094513-19} }

We apply heavy-quark effective theory to separate long- and short-distance effects of heavy quarks in lattice gauge theory. In this approach, the inverse heavy-quark mass and the lattice spacing are treated as short distances, and their effects are lumped into short-distance coefficients. We show how to use this formalism to match lattice gauge theory to continuum QCD, order by order in the heavy-quark expansion. In this paper, we focus on heavy-light currents. In particular, we obtain one-loop…
