改进规范action的静态夸克势的多级算法

The static quark potential from a multilevel algorithm for the improved gauge action

Anne Mykkanen

摘要:

本文推广Luescher和Weisz的多层算法,研究了SU(N)Yang-Mills理论在树层改进规范作用量下的性质.我们在2+1和3+1维的SU(3)和SU(4)Yang-Mills理论中测试了该算法,并将其结果与使用Wilson作用量得到的结果进行了比较。我们测量静态夸克势,并提取Luescher项,玻色子弦论预测。

英文摘要:

We generalize the multilevel algorithm of Luescher and Weisz to study SU(N) Yang-Mills theories with the tree-level improved gauge action. We test this algorithm, comparing its results with those obtained using the Wilson action, in SU(3) and SU(4) Yang-Mills theories in 2+1 and 3+1 dimensions. We measure the static quark potential and extract the Luescher term, predicted by the bosonic string theory.
