标题： Symanzik Improvement In The Static Quark Potential

摘要： 对静态夸克势在淬火QCD中的赛曼茨改进规范场行动进行了系统研究。 我们考虑了在16^3 X 32格子上，晶格间距相对较粗为0.165(2)fm的赛曼茨改进规范场构型。准备了一组匹配的标准 威尔逊规范构型\beta = 5.74 with 在相同的物理体积和晶格间距下，并用于比较研究。 我们发现，尽管晶格间距较粗，未改进且成本较低的威尔逊作用与赛曼茨作用一样好，使我们能够提取大qqbar分离时的静态夸克势。 我们已经考虑了静态夸克势中非轴向步进的新方法，这为基态势在威尔逊环关联函数中占据主导地位的程度提供了新的见解。 显示英文摘要

摘要： A systematic investigation of Symanzic improvement in the gauge field action is performed for the static quark potential in quenched QCD. We consider Symanzik improved gauge field configurations on a 16^3 X 32 lattice with a relatively coarse lattice spacing of 0.165(2)fm. A matched set of standard Wilson gauge configurations is prepared at \beta = 5.74 with the same physical volume and lattice spacing and is studied for comparison. We find that, despite the coarse lattice spacing, the unimproved and less-expensive Wilson action does as well as the Symanzik action in allowing us to extract the static quark potential at large qqbar separations. We have considered novel methods for stepping off-axis in the static quark potential which provides new insights into the extent to which the ground state potential dominates the Wilson loop correlation function.
