希格斯数据与退耦极限

The Higgs data and the Decoupling Limit

Howard E. Haber

摘要:

由ATLAS和CMS合作分析的希格斯数据表明,2012年发现的标量状态是一种类似标准模型(SM)的希格斯玻色子。尽管如此,在标准模型之外,希格斯物理学仍然有很大的空间。许多研究电弱对称破缺的方法都有一个退耦极限,在这个极限下,最轻的CP偶希格斯标量的性质接近SM希格斯玻色子的性质。在某些情况下,一个明显的类SM希格斯信号也可以出现在一个可能不受去耦限制的制度。如果观测到的希格斯信号是两个未分辨的近质量简并标量态的结果,那么这种情况就可以实现。一般的双Higgs二重态模型提供了一个有用的框架,研究退耦极限和可能偏离SM类Higgs行为。目前和未来的希格斯数据的影响进行了简要的考虑。

英文摘要:

The Higgs data analyzed by the ATLAS and CMS Collaborations suggest that the scalar state discovered in 2012 is a Standard Model (SM)--like Higgs boson. Nevertheless, there is still significant room for Higgs physics beyond the Standard Model. Many approaches to electroweak symmetry breaking possess a decoupling limit in which the properties of the lightest CP-even Higgs scalar approach those of the SM Higgs boson. In some cases, an apparent SM-like Higgs signal can also arise in a regime that may not be governed by the decoupling limit. One such scenario can be realized if the observed Higgs signal is a result of two unresolved nearly-mass-degenerate scalar states. The general two-Higgs doublet model provides a useful framework for studying the decoupling limit and possible departures from SM-like Higgs behavior. The implications for current and future Higgs data are briefly considered.
