NLO生产HJ中的顶夸克质量效应

Top quark mass effects in HJ production at NLO

Matthias Kerner

摘要:

我们提出了在QCD中与一个次领先级喷流相关联的胶子融合希格斯玻色子产生的预言。计算保留了对顶夸克质量的完全依赖。使用SecDec程序数值计算虚拟修正中出现的双环积分。我们展示了如何改变主积分可以提高计算的稳定性和运行时间。我们研究了希格斯玻色子的横向动量分布,并将我们的预测与近似结果进行了比较。

英文摘要:

We present predictions for gluon-fusion Higgs boson production in association with one jet at next-to-leading order in QCD. The calculation is performed retaining the full dependence on the top-quark mass. The two-loop integrals appearing in the virtual corrections are calculated numerically using the program SecDec. We show how a change of master integrals can improve the stability and runtime of the calculation. We study the Higgs boson transverse momentum distribution and compare our predictions with approximated results.
