Deconstructing Dimensional Deconstruction

Dimensional deconstruction (DD) abstracts from higher dimensional models features of related 4–dimensional ones. DD was proposed in Refs. [1–3] as a scheme for constructing models of naturally light composite Higgs boson. These are models in which—without fine–tuning of parameters—the composite Higgs’s mass M and vacuum expectation value v are much lighter than its binding energy scale Λ. We re...

QCD and dimensional deconstruction

Motivated by phenomenological models of hidden local symmetries and the ideas of dimensional deconstruction and gauge/gravity duality, we consider the model of an “open moose”. Such a model has a large number K of hidden gauge groups as well as a global chiral symmetry. In the continuum limit K → ∞ the model becomes a 4+1 dimensional theory of a gauge field propagating in a dilaton background a...

A Case Study in Dimensional Deconstruction

We test Arkani-Hamed et al.’s dimensional deconstruction on a model that is predicted to have a naturally light composite Higgs boson, i.e., one whose mass M is much less than its binding scale Λ, and whose quartic coupling λ is large, so that its vacuum expectation value v ∼ M/ √ λ ≪ Λ also. We consider two different underlying dynamics—UV completions—at the scale Λ for this model. We find tha...

Electroweak symmetry breaking from dimensional deconstruction

We propose a new class of four-dimensional theories for natural electroweak symmetry breaking, relying neither on supersymmetry nor on strong dynamics at the TeV scale. The new TeV physics is perturbative, and radiative corrections to the Higgs mass are finite. The softening of this mass occurs because the Higgs is an extended object in theory space, resulting in an accidental symmetry. A novel...

Dimensional Deconstruction and Wess–Zumino–Witten Terms

Abstract A new technique is developed for the derivation of the Wess-Zumino-Witten terms of gauged chiral lagrangians. We start in D = 5 with a pure (mesonless) Yang-Mills theory, which includes relevant gauge field Chern-Simons terms. The theory is then compactified, and the effective D = 4 lagrangian is derived using lattice techniques, or “deconstruction,” where pseudoscalar mesons arise fro...
