Holographic Completion of Minimal Neutral Naturalness Model and Deconstruction

Abstract

We previously presented the minimal neutral naturalness model, in which neutral naturalness is realized with the minimal coset and the minimal field content in the color-neutral sector. To fully eliminating the cutoff dependence in the Higgs potential, its ultraviolet completion was laid out. In this work, we investigate in details the holographic realization in warped five-dimensional framework. Using the holographic method, we obtain the effective action on the UV brane and derive the finite Higgs potential, with the Higgs being a pseudo Nambu-Goldstone boson. The Higgs potential is fully radiatively generated and vacuum misalignment is naturally realized through only the fermionic contribution. To illustrate general features of the lowest Kaluza-Klein states, we construct the corresponding deconstructed two-site composite model.
