Abstract
We show how to make O(a) corrections in the bare parameters of 3D latt ice SU(2)xU(1) Higgs theory, which remove O(a) errors in the match bet ween the infrared behavior and the infrared behavior of the continuum theory. The corrections substantially improve the convergence of latti ce data to a small a limit. (C) 1997 Elsevier Science B.V.
