Quark-mass effects in Higgs-boson production in gluon fusion (A1a)

在这个项目中，我们的目标是在微扰理论中通过高阶胶子聚变完全控制希格斯粒子产生中的夸克质量效应。这包括强耦合下四阶总截面和微分截面的顶夸克和底夸克质量效应的计算及其在蒙特-卡罗程序中的实现。在平行于这些量的精确评估，我们也将通过近似的评估和组合振幅的特征运动学限制的问题。所开发的方法还将使我们能够考虑标准模型之外的潜在物理效应。

In this project, we aim for a full control of quark-mass effects in Higgs production through gluon fusion at higher orders in perturbation theory. This includes the calculation of the top- and bottom-quark mass effects for the total and differential cross section at 4th order in the strong coupling and their implementation in Monte-Carlo programs. In parallel to the exact evaluation of these quantities, we will also approach the problem through approximations by evaluating and combining amplitudes in characteristic kinematical limits. The developed methods will also allow us to consider effects from potential physics beyond the Standard Model.
