TL;DR
This paper investigates how composite Higgs models with partial compositeness influence the Higgs mass, highlighting the correlation with top partner masses and implications for LHC searches.
Contribution
It extends previous analyses to different representations and cosets, revealing a strong link between top partner masses and the Higgs mass in composite models.
Findings
Higgs mass of 125 GeV suggests fermionic partners below TeV
Strong correlation between top partner and Higgs masses
Implications for LHC detection of top partners
Abstract
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.
