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