N3LO的包容性生产截面

Inclusive Production Cross Sections at N3LO

Julien Baglio, Claude Duhr, Bernhard Mistlberger, Robert Szafron

摘要:

本文首次给出了在QCD中伴随希格斯玻色子玻色子与大质量规范玻色子以次-领先阶产生的包含截面。此外,我们介绍了n3 loxs,一个公共的,数值程序的评估包括截面在第三阶强耦合常数。我们的工具可以得到预测带电和中性电流的Drell-Yan生产,胶子和底夸克融合希格斯玻色子生产和希格斯玻色子相关生产与重规范玻色子。我们讨论了上述过程的微扰和部分子分布函数(PDF)的不确定性。我们进行了比较的全球PDF集的各种过程,包括相关的希格斯玻色子生产和观察$1σ$偏差之间的预测几个过程。

英文摘要:

We present for the first time the inclusive cross section for associated Higgs boson production with a massive gauge boson at next-to-next-to-next-to-leading order in QCD. Furthermore, we introduce n3loxs, a public, numerical program for the evaluation of inclusive cross sections at the third order in the strong coupling constant. Our tool allows to derive predictions for charged- and neutral-current Drell-Yan production, gluon- and bottom-quark-fusion Higgs boson production and Higgs boson associated production with a heavy gauge boson. We discuss perturbative and parton distribution function (PDF) uncertainties of the aforementioned processes. We perform a comparison of global PDF sets for a variety of process including associated Higgs boson production and observe $1σ$ deviations among predictions for several processes.
