Abstract

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.
