# The Unhiggs

@inproceedings{Stancato2008TheU, title={The Unhiggs}, author={David Stancato and John Terning}, year={2008} }

We examine a scenario where the Higgs is part of an approximate conformal field theory, and has a scaling dimension greater than one. Such an unparticle Higgs (or Unhiggs) can still break electroweak symmetry and unitarize WW scattering, but its gauge couplings are suppressed. An Unhiggs model has a reduced sensitivity of the weak scale to the cutoff, and can thus provide a solution to the little hierarchy problem.

Holographic Unhiggs

We propose an extra-dimensional approach to the unparticle Higgs (Unhiggs). The non-local 4D Unhiggs action is derived as the boundary effective action of a local 5D theory. We review the mechanism…

Collider phenomenology of a gluino continuum

Continuum supersymmetry is a class of models in which the supersymmetric partners together with part of the standard model come from a conformal sector, broken in the IR near the TeV scale. Such…

Electroweak precision observables and the unhiggs

We compute one-loop corrections to the S and T parameters in the Unhiggs scenario. In that scenario, the Standard Model Higgs is replaced by a non-local object, called the Unhiggs, whose spectral…

Unparticle and Higgs boson as composites

We propose a generic framework in which the Higgs and the unparticle are both composite. The underlying theories are four-dimensional, asymptotically-free, nonsupersymmetric gauge theories with…

We develop a general set of methods for computing the oblique electroweak parameters S andT for bottom-up and top-down motivated scenarios in which the Higgs weakly mixes with a superconformal extra…

Non-local Higgs actions: tree-level electroweak constraints and high-energy unitarity

We consider electroweak symmetry breaking by a certain class of non-local Higgs sectors. Extending previous studies employing the Mandelstam condition, a straight Wilson line is used to make the…

A bstractWe present a novel class of composite Higgs models in which the top and gauge partners responsible for cutting off the Higgs quadratic divergences form a continuum. The continuum states are…

Invisible Higgs boson, continuous mass fields, and unparticle Higgs mechanism

We explore the consequences of an electroweak symmetry breaking sector which exhibits approximately scale invariant dynamics -- i.e., nontrivial fixed point behavior, as in unparticle models. One can…

We propose a general class of five-dimensional (5D) soft-wall models with AdS metric near the ultraviolet brane and 4D Poincare invariance, where the infrared scale is determined dynamically. A large…
