从平均元格中提取胶子凝聚

Extracting gluon condensate from the average plaquette

Taekoon Lee

摘要:

平均元格中的微扰贡献使用Borel求和减去,并且元格的剩余部分被示出为作为dim-4冷凝物的比例。一个严格的审查提出的renormalon减法计划,声称一个昏暗-2冷凝。将提取的胶子凝聚体与随机微扰论高阶(35圈)计算的最新结果进行了比较。

英文摘要:

The perturbative contribution in the average plaquette is subtracted using Borel summation and the remnant of the plaquette is shown to scale as a dim-4 condensate. A critical review is presented of the renormalon subtraction scheme that claimed a dim-2 condensate. The extracted gluon condensate is compared with the latest result employing high order (35-loop) calculation in the stochastic perturbation theory.
