AI 中文摘要
喷注 veto 在大型强子对撞机上对希格斯玻色子性质的精密测量中至关重要，它们被用于抑制包含硬 QCD 辐射的本底。我们首次给出了在 QCD 第三对数阶上希格斯喷注 veto 截面的预测，一致地结合了次次次领头阶计算与最先进的次次次领头对数重求和。在现象学相关的 veto 能标（$p_T^{\rm v}\sim30$ GeV）和喷注半径（$R=0.4$）下，重求和将固定阶预测提高了约 $3\\%$，它们的组合导致约 $3\\%$ 的残余微扰不确定性。我们的结果标志着在强子对撞机上精确描述喷注 veto 的希格斯产生的一个里程碑，达到了与 LHC 高亮度阶段相关的精度水平。
英文摘要
Jet vetoes are central to precision measurements of Higgs-boson properties at the Large Hadron Collider, where they are used to suppress backgrounds containing hard QCD radiation. We present the first prediction for the Higgs jet-vetoed cross section at the third logarithmic order in QCD, consistently combining the next-to-next-to-next-to-leading order calculation with state-of-the-art next-to-next-to-next-to-leading logarithmic resummation. At phenomenologically relevant veto scales ($p_T^{\rm v}\sim30$ GeV) and jet radii ($R=0.4$), the resummation increases the fixed-order prediction by about $3\%$, and their combination leads to a residual perturbative uncertainty of approximately $3\%$. Our results mark a milestone in the precise description of jet-vetoed Higgs-production at hadron colliders, reaching the level of precision relevant for the high-luminosity phase of the LHC.
