HPro:一个NLO Monte-Carlo计算有限重夸克质量胶子聚变产生Higgs

HPro: A NLO Monte-Carlo for Higgs production via gluon fusion with finite heavy quark masses

Charalampos Anastasiou, Stefan Bucherer, Zoltan Kunszt

摘要:

在标准模型中,计算了希格斯玻色子通过胶子融合产生的全微分次至首阶QCD截面。我们保持完全依赖于顶夸克和底夸克质量的截面。我们发现,有限夸克质量的影响是重要的QCD预测胶子融合的精度。我们的蒙特卡罗程序,HPro,可以纠正现有的NNLO全微分计算,采用近似的一个无限重的顶部和一个消失的底部夸克汤川耦合,重夸克有限质量效应通过NLO。

英文摘要:

We compute fully differential next-to-leading order QCD cross-sections for Higgs boson production via gluon fusion in the Standard Model. We maintain the full dependence of the cross-sections on the top and bottom quark mass. We find that finite quark mass effects are important given the achieved precision of QCD predictions for gluon fusion. Our Monte-Carlo program, HPro, can correct existing NNLO fully differential calculations, which employ the approximation of an infinitely heavy top and a vanishing bottom quark Yukawa coupling, for heavy quark finite mass effects through NLO.
