在QCD中N $^3$ LO上矢量玻色子融合Higgs的产生

Vector-boson fusion Higgs production at N$^3$LO in QCD

Frédéric A. Dreyer, Alexander Karlberg

摘要:

在两个碰撞质子的强子系统之间没有颜色交换的极限下,计算了质子对撞机上包含矢量-玻色子融合(VBF)Higgs产生的次-领先级(N $^3$ LO)QCD修正.我们还提供了微分截面的希格斯横向动量和快度分布。我们发现,修正是在1-2 permille的水平,以及在规模的不确定性的下一个到下一个到领先的顺序(NNLO)计算。通常发现N $^3$ LO计算的相关标度不确定度低于2千分之一水平。我们还考虑了由于缺少高阶部分子分布函数的理论不确定性,并提供了它们的重要性的估计。

英文摘要:

We calculate the next-to-next-to-next-to-leading-order (N$^3$LO) QCD corrections to inclusive vector-boson fusion (VBF) Higgs production at proton colliders, in the limit in which there is no colour exchange between the hadronic systems associated with the two colliding protons. We also provide differential cross sections for the Higgs transverse momentum and rapidity distributions. We find that the corrections are at the 1-2 permille level, well within the scale-uncertainty of the next-to-next-to-leading-order (NNLO) calculation. The associated scale-uncertainty of the N$^3$LO calculation is typically found to be below the 2 permille level. We also consider theoretical uncertainties due to missing higher order parton distribution functions, and provide an estimate of their importance.
