在QCD的N3LO强子对撞机上的希格斯玻色子产生

Higgs Boson Production at Hadron Colliders at N3LO in QCD

Bernhard Mistlberger

摘要:

本文给出了强子对撞机上通过微扰QCD中的N3LO在胶子聚变产生模式下的希格斯玻色子产生截面。具体来说,我们在一个有效的理论中工作,其中顶夸克被假设为无限重,所有其他夸克被认为是无质量的。我们的结果是微扰QCD中N3LO部分子强子碰撞截面的第一个精确公式。此外,这一结果代表了强子对撞机截面的第一个解析计算涉及椭圆积分。我们推导出大型强子对撞机中希格斯玻色子截面的数值预测。以前,这个结果是近似的横截面周围的希格斯玻色子的生产阈值的扩展,我们比较我们的研究结果。最后,我们研究了我们的新结果对LHC中希格斯玻色子截面的最新预测的影响。

英文摘要:

We present the Higgs boson production cross section at Hadron colliders in the gluon fusion production mode through N3LO in perturbative QCD. Specifically, we work in an effective theory where the top quark is assumed to be infinitely heavy and all other quarks are considered to be massless. Our result is the first exact formula for a partonic hadron collider cross section at N3LO in perturbative QCD. Furthermore, this result represents the first analytic computation of a hadron collider cross section involving elliptic integrals. We derive numerical predictions for the Higgs boson cross section at the LHC. Previously this result was approximated by an expansion of the cross section around the production threshold of the Higgs boson and we compare our findings. Finally, we study the impact of our new result on the state of the art prediction for the Higgs boson cross section at the LHC.
