Description

For operators in lattice gauge theories linear in the link variables we propose improved estimators, obtained from a microcanonical integration of statistically independent links. We give explicit analytic expressions for the SU(2) and the SU(3) cases and we compare the method with the canonical integration based on the multihit technique. (orig.)
