Tevatron上的希格斯物理学

Higgs physics at the Tevatron

Fabrizio Margaroli

摘要:

我们展示了CDF和D 0合作研究希格斯玻色子的最新结果,这些结果源自对整个Tevatron Run\,II数据集的分析。结合许多个体分析的结果,其中大多数使用完整的数据集,在希格斯玻色子质量为125\,GeV/ $c^2$时,观察到相对于标准模型假设约三个标准差的显著性过剩。Tevatron独特的环境允许除了第一次研究希格斯玻色子的自旋宇称假设在事件中,它衰变为夸克。在目前的实验不确定性,新发现的玻色子的行为所预期的费米部门的SM。

英文摘要:

We show the latest results from the CDF and D0 collaborations on the study of the Higgs boson, stemming from the analysis of the entire Tevatron Run\,II dataset. Combining the results of many individual analyses, most of which use the full data set available, an excess with a significance of approximately three standard deviations with respect to the Standard Model hypothesis is observed at a Higgs boson mass of 125\,GeV/$c^2$. The Tevatron unique environment allows in addition to study for the first time the spin-parity hypothesis of the Higgs boson in events where it decays to quarks. Within the current experimental uncertainties, the newly discovered boson behaves as expected by the SM in the fermionic sector.
