Deconstruction and holography

Deconstruction and Holography

It was recently pointed out that the physics of a single discrete gravitational extra dimension exhibits a peculiar UV/IR connection relating the UV scale to the radius of the effective extra dimension. Here we note that this non-locality is a manifestation of holography, encoding the correct scaling of the number of fundamental degrees of freedom of the UV theory. This in turn relates the Wils...

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...

Spherical Deconstruction

We present evidence that N = 1 * SUSY Yang-Mills provides a decon-struction of a six-dimensional gauge theory compactified on a two-sphere. The six-dimensional theory is a twisted compactification of N = (1, 1) SUSY Yang-Mills theory of the type considered by Maldacena and Nunez (MN) in [1]. In particular, we calculate the full classical spectrum of the N = 1 * theory with gauge group U (N) in ...

Deconstruction and Bilarge Neutrino Mixing

We present a model for lepton masses and mixing angles using the deconstruction setup, based on a non-Abelian flavor symmetry which is a split extension of the Klein group Z2 × Z2. The symmetries enforce an approximately maximal atmospheric mixing angle θ23, a nearly vanishing reactor mixing angle θ13, and the hierarchy of charged lepton masses. The charged lepton mass spectrum emerges from the...
