Progress in automated perturbation theory for heavy quark physics
arXiv:hep-lat/0309086 · doi:10.1016/S0920-5632(03)02580-5
Abstract
We review our perturbative techniques for improved heavy quark actions. A new procedure for computing improvement coefficients is suggested, where the continuum limit of a lattice-regularized theory provides the matching conditions.We also use a gauge-invariant infrared regulator that is well suited to higher-order calculations in lattice gauge theory. We report on preliminary tests of our method, as well as a possible way to reduce systematic errors in these calculations.
