Successful application on RBC's 16^3 x 32 lattice ensemble

Potential for improved non-perturbative renormalization techniques

Abstract

We report on progress to renormalize non-pertubatively the static heavy quark theory on the lattice. In particular, we present first results for position-space renormalization scheme for heavy-light bilinears. We test our approach on RBC's 16^3 x 32 lattice ensemble with m_pi = 420 MeV, Iwasaki gauge action and domain wall light fermions.
