Phys. Rev. D 62, 114006 (2000) [19 pages]Renormalization of the lattice heavy quark effective theory Isgur-Wise functionReceived 23 December 1999; published 23 October 2000 We compute the perturbative renormalization factors required to match to the continuum Isgur-Wise function, calculated using lattice heavy quark effective theory. The velocity, mass, wave function, and current renormalizations are calculated for both the forward-difference and backward-difference actions for a variety of velocities. Subtleties are clarified regarding tadpole improvement, regulating divergences, and variations of techniques used in these renormalizations. © 2000 The American Physical Society URL:
