Abstract: | In the extra dimensional scenarios with gauge fields in the bulk, the Kaluza-Klein (KK) gauge bosons can induce Nambu-Jona-Lasinio
(NJL) type attractive fourfermion interactions, which can break electroweak symmetry dynamically with accompanying composite
Higgs fields. We consider a possibility that electroweak symmetry breaking (EWSB) is triggered by both a fundamental Higgs
and a composite Higgs arising in a dynamical symmetry breaking mechanism induced by a new strong dynamics. The resulting Higgs
sector is a partially composite two-Higgs doublet model with specific boundary conditions on the coupling and mass parameters
originating at a compositeness scale Λ. The phenomenology of this model is discussed including the collider phenomenology
at LHC and ILC.
