摘要

研究了朗道测量条件下的点阵离散误差。提出了一种改进的消去0 (a{sup 2})误差的测规固定算法。O(a{sup 2})固定条件的改善从两个方面改善了与连续体朗道仪的比较:(1)通过消除O(a{sup 2})误差和(2)通过减小高阶误差大小的二次效应。这些结果强调了改进测规固定条件的重要性。

Discretisation errors in Landau gauge on the lattice

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