Higgs-Glue扇区中八维算子的双环匹配
Two-Loop Matching onto Dimension Eight Operators in the Higgs-Glue Sector
摘要：
这封信介绍了两个循环匹配系数的八维运营商，有助于通过胶子融合希格斯生产的结果。这些系数可以用来计算在两个环上对具有大横向动量的希格斯粒子产生的无限大质量上限的第一修正。到目前为止，这样的过程已经研究了两个循环的顺序，只有在领先的长期在顶部的质量膨胀。这些修正成为增强的过程中具有大的最终状态不变质量，典型的多射流过程。
英文摘要：
This letter presents results for the two-loop matching coefficients for the dimension eight operators that contribute to Higgs production via gluon fusion. The coefficients can be used to calculate the first correction to the infinite top mass limit to Higgs production with large transverse momentum at two loops. To date such processes have been studied at two loop order only in the leading term in the top mass expansion. These corrections become enhanced in processes with large final state invariant mass, typical of multijet processes.
