Abstract
Lattice discretisation errors in the Landau gauge condition are examined. An improved gauge fixing algorithm in which ?(a2) errors are removed is presented. ?(a2) improvement of the gauge fixing condition improves comparison with the continuum Landau gauge in two ways: (1) through the elimination of ?(a2) errors and (2) through a secondary effect of reducing the size of higher-order errors. These results emphasise the importance of implementing an improved gauge fixing condition.Keywords
