A natural composite Higgs via universal boundary conditions

We present a novel realization of a composite Higgs, which can naturally produce top partners above the current LHC bounds without increasing the tuning above 10%. The essential ingredients are softened breaking of the Higgs shift symmetry as well as maximal symmetry, which turn out to perfectly complement each other. The 5D realization of this model is particularly simple: universal UV and IR boundary conditions for the bulk fermions containing the SM fields will cure the problems of existing holographic composite Higgs models and provide a complete viable model for a naturally light Higgs without much tuning.

Automated summary

The composite Higgs model presented in this study combines softened breaking of the Higgs shift symmetry with maximal symmetry to naturally produce top partners without significantly increasing tuning. The 5D realization of this model simplifies with universal UV and IR boundary conditions for bulk fermions containing SM fields, providing a viable solution for a naturally light Higgs.
