Non-perturbative Heavy Quark Effective Theory: a test and its matching to QCD
Rainer Sommer
Abstract
We give an introduction to the special problems encountered in a treatment of HQET beyond perturbation theory in the gauge coupling constant. In particular, we report on a recent test of HQET as an effective theory for QCD and discuss how HQET can be implemented on the lattice including the non-perturbative matching of the effective theory to QCD.
