摘要:

本文研究了在LHC和100 TeV强子对撞机上,依赖顶夸克质量的双圈修正对胶子聚变产生希格斯玻色子玻色子对的影响.我们进行了详细的比较完整的次领先的顺序的结果,在差分分布的水平上的各种近似,并分析非标准的希格斯自耦合的情况。我们发现,不同的次领先阶近似的差异高达50%,从完整的结果在相关的微分分布。这清楚地强调了完整NLO结果的重要性。

英文摘要:

We study the effects of the exact top-quark mass dependent two-loop corrections to Higgs boson pair production by gluon fusion at the LHC and at a 100 TeV hadron collider. We perform a detailed comparison of the full next-to-leading order result to various approximations at the level of differential distributions and also analyse non-standard Higgs self-coupling scenarios. We find that the different next-to-leading order approximations differ from the full result by up to 50 percent in relevant differential distributions. This clearly stresses the importance of the full NLO result.
