反常标准模型相互作用下希格斯玻色子强子产生的总截面

Total cross-section for Higgs boson hadroproduction with anomalous Standard Model interactions

Charalampos Anastasiou, Stephan Buehler, Franz Herzog, Achilleas Lazopoulos

摘要:

本文介绍了一个计算强子对撞机上包含的希格斯玻色子截面的新程序iHixs。它包括QCD修正通过NNLO,实和虚电弱修正,混合QCD-电弱修正,夸克质量效应通过非线性光学QCD,和有限宽度效应的希格斯玻色子和重夸克。iHixs可用于在标准模型中获得固定阶微扰理论中最精确的横截面值。此外,它允许修改后的希格斯玻色子部门与异常汤川和电弱相互作用的标准模型的扩展所需的横截面的一致评价。iHixs与LHAPDF库接口,可与所有可用的部分子分布函数NNLO集一起使用。

英文摘要:

We present a new program (iHixs) which computes the inclusive Higgs boson cross-section at hadron colliders. It incorporates QCD corrections through NNLO, real and virtual electroweak corrections, mixed QCD-electroweak corrections, quark-mass effects through NLO in QCD, and finite width effects for the Higgs boson and heavy quarks. iHixs can be used to obtain the most precise cross-section values in fixed order perturbation theory in the Standard Model. In addition, it allows for a consistent evaluation of the cross-section in modified Higgs boson sectors with anomalous Yukawa and electroweak interactions as required in extensions of the Standard Model. iHixs is interfaced with the LHAPDF library and can be used with all available NNLO sets of parton distribution functions.
