Softened Symmetry Breaking in Composite Higgs Models

Abstract

We propose a new way of breaking the Goldstone symmetry in composite Higgs models, restoring the global symmetry in the mixings between the elementary and composite fermions by completing the former to full representations of this symmetry. The Goldstone symmetry is in turn broken softly by vectorlike mass terms in the elementary sector only. The resulting softened explicit breaking allows for a light Higgs boson, as found at the LHC, and a heavy top quark, without the need of light top partners around the Goldstone scale fTeVmcomp., which remain elusive at the LHC, while we recover the standard scenario in the limit of infinite vectorlike masses.
