Non-Perturbative Improvement of the Anisotropic Wilson QCD Action
Abstract
We describe the first steps in the extension of the Symanzik O(a) improvement program for Wilson-type quark actions to anisotropic lattices, with a temporal lattice spacing smaller than the spatial one. This provides a fully relativistic and computationally efficient framework for the study of heavy quarks. We illustrate our method with accurate results for the quenched charmonium spectrum.
