LHC的希格斯粒子产生:更新了$\sqrt{s}=8$ TeV的截面

Higgs production at the LHC: updated cross sections at $\sqrt{s}=8$ TeV

D. de Florian, M. Grazzini

摘要:

我们预测了在$\sqrt{s}=8$ TeV质子碰撞中胶子-胶子融合产生希格斯玻色子的包容截面。我们的计算是精确到次至次至主导阶QCD微扰理论,并包括软胶子效应的次至次至主导对数精度和两圈电弱修正。对重夸克质量的依赖关系被精确地考虑到次领先阶和次领先对数精度,并且根据复极方案提供了对希格斯玻色子玻色子线形的处理。

英文摘要:

We present predictions for the inclusive cross section for Higgs boson production by gluon--gluon fusion in proton collisions at $\sqrt{s}=8$ TeV. Our calculation is accurate up to next-to-next-to-leading order in QCD perturbation theory and includes soft-gluon effects up to next-to-next-to-leading logarithmic accuracy and two-loop electroweak corrections. The dependence on heavy-quark masses is taken into account exactly up to next-to-leading order and next-to-leading logarithmic accuracy, and a treatment of the Higgs boson line-shape is provided according to the complex-pole scheme.
