NNLO下的希格斯玻色子对产生

Higgs pair production at NNLO

Joshua Davies

AI总结:

该研究推进了胶子融合中希格斯对产生的NNLO虚修正计算,基于前向散射极限展开,可在更宽相空间估算三圈虚修正的大小与不确定性,补充了现有大顶夸克质量极限展开的结果。

摘要:

在本次报告中,我汇报了围绕前向散射极限展开、胶子融合过程中希格斯玻色子对产生的次次领头阶(NNLO)虚修正计算的进展。该计算结果将能在比现有文献结果大得多的相空间区域内,估算三圈虚修正的大小和不确定性;现有文献结果基于大顶夸克质量极限下的展开得到。

英文摘要:

In this talk I report on progress towards the computation of the next-to-next-to-leading order virtual corrections to Higgs boson pair production in gluon fusion, in an expansion around the forward-scattering limit. The results of this computation will provide an estimate of the size and uncertainty of the three-loop virtual corrections in a comparatively much larger region of phase space than the results available in the literature, which are based on an expansion in the limit of a large top quark mass.
