交错双线性算子的改进胶合单圈匹配因子

One loop matching factors for staggered bilinear operators with improved glue

Jongjeong Kim, Weonjong Lee, Stephen R. Sharpe

摘要:

我们目前的结果,由HYP涂抹交错费米子和使用HYP涂抹脂肪链接构建的双线性算子的匹配因子。匹配因子的计算微扰在一个循环的顺序。我们的计算的新功能相比,以前的工作HYP涂抹交错费米子是使用西曼齐克改进胶子传播子,这使得我们的结果被应用到我们正在进行的模拟的基础上产生的配置MILC合作。我们解决的问题的相对效率的各种改进方案,在减少单回路校正的匹配因子。

英文摘要:

We present results for matching factors for bilinear operators composed of HYP-smeared staggered fermions and constructed using HYP-smeared fat links. The matching factors are calculated perturbatively at one-loop order. The new feature of our calculation compared to previous work on HYP-smeared staggered fermions is the use of the Symanzik-improved gluon propagator, which allows our results to be applied to our ongoing simulations based on configurations generated by the MILC collaboration. We address the issue of the relative efficiency of various improvement schemes in reducing one-loop corrections to the matching factors.
