关于理论不确定性对Tevatron Higgs排除极限的影响的澄清

Clarifications on the impact of theoretical uncertainties on the Tevatron Higgs exclusion limits

Julien Baglio, Abdelhak Djouadi, Rohini Godbole

摘要:

在本文中,我们回应了CDF和D0合作的代表对我们最近的论文所作的评论和批评,我们在这些论文中指出,希格斯粒子产生截面中的理论不确定性在很大程度上被低估了,如果适当考虑,将大大放松Tevatron希格斯粒子排斥边界。我们表明,我们的理论不确定性的方法是合理的,完全合理的。特别是,我们表明,我们的程序是不是很不同的LHC实验所采用的,如果后者是用于Tevatron的情况下,一个得到更大的不确定性,CDF和D0合作所假设的。此外,我们还提供了CDF和D0排除限统计分析的更多详细信息,并表明其在概念上是正确的。

英文摘要:

In this note, we respond to the comments and criticisms made by the representatives of the CDF and D0 collaborations on our recent papers in which we point out that the theoretical uncertainties in the Higgs production cross section have been largely un- derestimated and, if properly taken into account, will significantly loosen the Tevatron Higgs exclusion bounds. We show that our approach to the theoretical uncertainties is reasonable and fully justified. In particular, we show that our procedure is not very different from that adopted by the LHC experiments and if the latter is used in the Tevatron case, one obtains much larger uncertainties that those assumed by the CDF and D0 collaborations. Furthermore, we provide additional details on our statistical analysis of the CDF and D0 exclusion limit and show that it is conceptually correct.
