在LHC上希格斯玻色子产生中的重夸克质量效应

Heavy-quark mass effects in Higgs boson production at the LHC

M. Grazzini, H. Sargsyan

摘要:

我们研究了重夸克质量对大型强子对撞机胶子融合产生希格斯玻色子的影响。考虑到有限的顶夸克和底夸克质量,我们将以前对希格斯玻色子的全微分截面和横动量谱的计算推广到O(α_S^3)。我们还讨论了当重夸克质量比希格斯质量小得多时所产生的问题。我们的研究结果在更新版本的HNNLO和HRes数值程序中实现。

英文摘要:

We study the impact of heavy-quark masses in Higgs boson production through gluon fusion at the LHC. We extend previous computations of the fully differential cross section and of the transverse momentum spectrum of the Higgs boson by taking into account the finite top- and bottom-quark masses up to O(alpha_S^3). We also discuss the issues arising when the heavy-quark mass is much smaller than the Higgs mass. Our results are implemented in updated versions of the HNNLO and HRes numerical programs.
