对LHC上矢量玻色子融合中希格斯玻色子产生的电弱和QCD修正

Electroweak and QCD corrections to Higgs-boson production in vector-boson fusion at the LHC

Mariano Ciccolini, Ansgar Denner, Stefan Dittmaier

摘要:

本文对LHC弱玻色子融合通道中希格斯玻色子玻色子产生的强相互作用和电弱相互作用的辐射修正进行了次领先级的计算。计算包括所有的弱玻色子融合和夸克-反夸克湮灭图以及所有相关的干扰。电弱修正也包括来自入射光子的实修正和两圈级的重希格斯玻色子效应,与QCD修正的大小相同,即对于质量高达\sim 700 GeV的希格斯玻色子,通常在5-10%的水平。一般来说,它们不会简单地重新调整微分分布,而是在10%的水平上引起失真。讨论的校正已在一个灵活的蒙特卡罗事件发生器中实现。

英文摘要:

Radiative corrections of strong and electroweak interactions are presented at next-to-leading order for Higgs-boson production in the weak-boson-fusion channel at the LHC. The calculation includes all weak-boson fusion and quark-antiquark annihilation diagrams as well as all related interferences. The electroweak corrections, which also include real corrections from incoming photons and leading heavy-Higgs-boson effects at two-loop order, are of the same size as the QCD corrections, viz. typically at the level of 5-10% for a Higgs-boson mass up to \sim 700 GeV. In general, they do not simply rescale differential distributions, but induce distortions at the level of 10%. The discussed corrections have been implemented in a flexible Monte Carlo event generator.
