希格斯粒子中的软胶子加上两个喷流的产生

Soft gluons in Higgs plus two jet production

Jeff Forshaw, Malin Sjodahl

摘要:

本文研究了软胶子发射的全阶QCD重建对两个硬喷注产生希格斯玻色子的影响。我们考虑了胶子-胶子融合和弱玻色子融合过程,并展示了如何在喷注否决尺度中恢复大部分的主导过程。我们的重新计算改进了以前的分析,其目的也是包括多重软胶子辐射的影响。此外,我们还计算了弱玻色子融合与胶子-胶子融合之间的干涉,发现干涉很小。

英文摘要:

We investigate the effects of an all order QCD resummation of soft gluon emissions for Higgs boson production in association with two hard jets. We consider both the gluon-gluon fusion and weak boson fusion processes and show how to resum a large part of the leading logarithms in the jet veto scale. Our resummation improves on previous analyses which also aim to include the effects of multiple soft gluon radiation. In addition we calculate the interference between weak boson fusion and gluon-gluon fusion and find that it is small.
