Abstract
An analytic method of smearing link variables in lattice QCD is proposed and
tested. The differentiability of the smearing scheme with respect to the link
variables permits the use of modern Monte Carlo updating methods based on
molecular dynamics evolution for gauge-field actions constructed using such
smeared links. In examining the smeared mean plaquette and the static
quark-antiquark potential, no degradation in effectiveness is observed as
compared to link smearing methods currently in use, although an increased
sensitivity to the smearing parameter is found.
