Deconstructing Dimensional Deconstruction
نویسنده
چکیده
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 review the basic idea of DD. It is easy to arrange M Λ. We show, however, that DD fails to give v Λ in a model that is supposed to contain a naturally light composite Higgs [4].

Seesaw neutrino masses with large mixings from dimensional deconstruction.
We demonstrate a dynamical origin for the dimension-five seesaw operator in dimensional deconstruction models. Light neutrino masses arise from the seesaw scale which corresponds to the inverse lattice spacing. It is shown that the deconstructing limit naturally prefers maximal leptonic mixing. Higher-order corrections which are allowed by gauge invariance can transform the bimaximal into a bil...
متن کاملDeconstructing KK Monopoles
We describe a procedure for finding Kaluza-Klein monopole solutions in deconstructed four and five dimensional supersymmetric gauge theories. In the deconstruction of a four dimensional theory, the KK monopoles are finite-action solutions of the Euclidean equations of motion of the finite lattice spacing theory. The “lattice” KK monopoles can be viewed as constituents of continuum-limit four di...
متن کاملTradition, Betrayal, and the Politics of Deconstruction
Using deconstructive techniques to make political and legal arguments raises the obvious question whether there is any connection between deconstruction and politics or deconstruction and justice. In fact, I believe that there are important connections between deconstruction, justice, and politics. But deconstruction itself does not have a politics, or rather, it has only the politics of those ...
متن کاملDeconstructing the Cosmological Constant
Deconstruction provides a novel way of dealing with the notoriously difficult ultraviolet problems of four-dimensional gravity. This approach also naturally leads to a new perspective on the holographic principle, tying it to the fundamental requirements of unitarity and diffeomorphism invariance, as well as to a new viewpoint on the cosmological constant problem. The numerical smallness of the...
متن کاملDeconstructing six dimensional gauge theories with strongly coupled moose meshes
It has recently been realized that five dimensional theories can be generated dynamically from asymptotically free, QCD-like four dimensional dynamics via “deconstruction.” In this paper we generalize this construction to six dimensional theories using a moose mesh with alternating weak and strong gauge groups. A new ingredient is the appearance of self couplings between the higher dimensional ...
