We study electroweak symmetry breaking involving the seesaw mechanism of quark condensation. These models produce a composite Higgs boson involving the left-handed top quark, yet the top mass arises naturally at the observed scale. We describe a schematic model which illustrates the general dynamical ideas. We also consider a generic low-energy effective… (More)

In this note we examine the properties of deconstructed Higgsless models for the case of a fermion whose SU (2) properties arise from delocalization over many sites of the deconstructed lattice. We derive expressions for the correlation functions and use these to establish a generalized consistency relation among correlation functions. We discuss the form… (More)

We analyze the spectrum and properties of a highly-deconstructed Higgsless model with only three sites. Such a model contains sufficient complexity to incorporate interesting physics issues related to fermion masses and electroweak observables, yet remains simple enough that it could be encoded in a Matrix Element Generator program for use with Monte Carlo… (More)

The triviality of the scalar sector of the standard one-doublet Higgs model implies that this model is only an effective low-energy theory valid below some cutoff scale Λ. For a heavy higgs this scale must be relatively low (10 TeV or less). Additional interactions coming from the underlying theory, and suppressed by the scale Λ, give rise to… (More)

Compactified five dimensional Yang-Mills theory results in an effective four-dimensional theory with a Kaluza-Klein (KK) tower of massive vector bosons. We explicitly demonstrate that the scattering of the massive vector bosons is unitary at tree-level for low energies, and analyze the relationship between the unitarity violation scale in the KK theory and… (More)

The low-energy properties of a compactified five-dimensional gauge theory can be reproduced in a four-dimensional theory with a replicated gauge group and an appropriate gauge symmetry breaking pattern. The lightest vector bosons in these " deconstructed " or " remodeled " theories have masses and couplings approximately equal to those of the Kaluza-Klein… (More)

In this study we investigated whether a visual illusion located in far space alters a person's open-loop, target-directed walking path in the same manner as it alters the perception of the target's position. Through the use of immersive VR the subject was able to walk physically to the location of a target embedded in a scene that was manipulated to create… (More)

We calculate the form of the corrections to the electroweak interactions in the class of Higgsless models which can be " deconstructed " to a chain of SU (2) gauge groups adjacent to a chain of U (1) gauge groups, and with the fermions coupled to any single SU (2) group and to any single U (1) group along the chain. The primary advantage of our technique is… (More)

In this note we calculate the form of electroweak corrections in deconstructed Higgsless models for the case of a fermion whose weak properties arise from two adjacent SU (2) groups on the deconstructed lattice. We show that, as recently proposed in the continuum , it is possible for the value of the electroweak parameter αS to be small in such a model. In… (More)
