本文首次对希格斯产生中的非全局对数进行次领头对数重求和，结合硬/软匹配函数与两圈反常维度，发现硬匹配修正主导且大于Drell-Yan，为对数精确簇射提供基准。
AI 中文摘要
我们分析了大型强子对撞机上中心快度区带喷注 veto 的希格斯产生过程，并首次给出了该过程非全局对数的次领头对数重求和。该重求和结合了大 $N_c$ 极限下的单圈硬匹配函数和软匹配函数以及两圈反常维度。为执行重求和，我们通过部分子簇射框架 MARZILI 数值求解重整化群方程。在与固定阶结果匹配后，我们对不同来源的不确定性进行了详细研究。我们发现硬匹配修正占主导地位，且远大于 Drell-Yan 产生过程中的相应修正。结合早先对 Drell-Yan 的结果，这些是强子对撞机截面中次领头非全局对数的首次重求和，并为对数精确的部分子簇射提供了基准。
英文摘要
We analyze Higgs production at the LHC with a jet veto at central rapidities and present the first next-to-leading logarithmic resummation of non-global logarithms for this process. The resummation combines one-loop hard and soft matching functions with two-loop anomalous dimensions in the large-$N_c$ limit. To perform the resummation we numerically solve renormalization group equations via the parton-shower framework MARZILI. After matching to fixed order, we perform a detailed study of different sources of uncertainties. We find that the hard matching corrections dominate by far and are substantially larger than in Drell-Yan production. Together with earlier results for Drell-Yan, these are the first resummations of subleading non-global logarithms in hadron-collider cross sections, and they provide a benchmark for logarithmically accurate parton showers.
