Holographic Twin Higgs Model

We present the first realization of a twin Higgs model as a holographic composite Higgs model. Uniquely among composite Higgs models, the Higgs potential is protected by a new standard model (SM) singlet elementary mirror sector at the sigma model scale f and not by the composite states at m(KK), naturally allowing for m(KK) beyond the LHC reach. As a result, naturalness in our model cannot be constrained by the LHC, but may be probed by precision Higgs measurements at future lepton colliders, and by direct searches for Kaluza-Klein excitations at a 100 TeV collider.
