在次次领头阶QCD的Higgs产生中的最高质量效应:虚拟修正

Top mass effects in Higgs production at next-to-next-to-leading order QCD: virtual corrections

Robert V. Harlander, Kemal J. Ozeren

摘要:

在三圈水平上计算了胶子聚变中Higgs产生的虚振幅O(α s^3)的顶夸克质量抑制项。自动形式的渐近展开法用于计算前三个非零阶的M_H^2/M_t^2,其中第一阶对应于有效拉格朗日方法的已知结果。

英文摘要:

Top quark mass suppressed terms are calculated for the virtual amplitude for Higgs production in gluon fusion at three-loop level, i.e. O(α_s^3). The method of asymptotic expansions in its automated form is used to evaluate the first three non-vanishing orders in terms of M_H^2/M_t^2, where the first order corresponds to the known results of the effective Lagrangian approach.
