Long Chen, Gudrun Heinrich, Stephen P. Jones, Matthias Kerner, Jonas Klappert, Johannes Schlenk

摘要:

我们提出的结果为双圈螺旋振幅进入非线性光学QCD修正的生产希格斯玻色子与$Z$-玻色子在胶子融合。数值计算了包含大质量顶夸克的双圈积分。的两个回路的振幅与玻恩振幅的有限部分的干扰的结果示出作为振幅依赖的两个运动学不变量的函数。

英文摘要:

We present results for the two-loop helicity amplitudes entering the NLO QCD corrections to the production of a Higgs boson in association with a $Z$-boson in gluon fusion. The two-loop integrals, involving massive top quarks, are calculated numerically. Results for the interference of the finite part of the two-loop amplitudes with the Born amplitude are shown as a function of the two kinematic invariants on which the amplitudes depend.
