PHYSICAL REVIEW D, Volume 65, Issue 11, 11 pp. https://doi.org/10.1103/PhysRevD.65.1150010556-2821https://hdl.handle.net/2144/40016We test dimensional deconstruction on a model of Arkani-Hamed, Cohen, and Georgi 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 that the expectation from dimensional deconstruction is not realized and that low-energy details depend crucially on the UV completion. In one case, M≪Λ and λ≪1; hence, v∼Λ. In the other, λ can be large or small, but then so is M, and v is still O(Λ).11 pagesen-US©2002 American Physical SocietyScience & technologyPhysical sciencesAstronomy & astrophysicsPhysics, particles & fieldsPhysicsSymmetry-breakingElectroweakNuclear & particles physicsAstronomical and space sciencesAtomic, molecular, nuclear, particle and plasma physicsQuantum physicsArticle10.1103/PhysRevD.65.1150010000-0001-8281-5438 (Lane, K)184672
