复合模型中轻希格斯粒子的意义

Implications of a Light Higgs in Composite Models

Michele Redi, Andrea Tesi

摘要:

本文研究了具有部分复合性的复合Higgs模型中的Higgs质量,将文献[1]的结果推广到SO(5)/SO(4)和陪集SO(6)/SO(5)的复合扇区的不同表示.对于一个给定的调谐,我们发现在一般的强相关性之间的质量的顶部合作伙伴和希格斯质量,类似于一个在超对称性。如果这个理论是自然的,那么125 GeV的希格斯质量通常需要低于TeV的费米子伙伴,这可能在目前LHC的范围内。还讨论了这两个陪集的CP性质。

英文摘要:

We study the Higgs mass in composite Higgs models with partial compositeness, extending the results of Ref. [1] to different representations of the composite sector for SO(5)/SO(4) and to the coset SO(6)/SO(5). For a given tuning we find in general a strong correlation between the mass of the top partners and the Higgs mass, akin to the one in supersymmetry. If the theory is natural a Higgs mass of 125 GeV typically requires fermionic partners below TeV which might be within the reach of the present run of LHC. A discussion of CP properties of both cosets is also presented.
