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 function displays a continuum above the mass gap. The Unhiggs propagator has effectively the same UV properties as the Standard Model Higgs propagator, which implies that loop corrections to the electroweak precision observables are finite and calculable. We show that the Unhiggs is consistent with…

Suppressing electroweak precision observables in 5D warped models
We elaborate on a recently proposed mechanism to suppress large contributions to the electroweak precision observables in five dimensional (5D) warped models, without the need for an extended 5D
Phenomenology of non-custodial warped models
We study the effect of bulk fermions on electroweak precision observables in a recently proposed model with warped extra dimensions and no custodial symmetry. We find that the top-quark mass,
Constraints on the Unhiggs Model from Top Quark Decay
We compute the top quark decay rate in the unHiggs model. In this model, the longitudinally polarized W's are unparticles, which is owed to their Goldstone boson nature, while the transversely

We present results from a model-independent analysis of the current constraints on new physics corrections to the Standard Model Higgs interactions based on the HEPfit package. We combine
Continuum superpartners from supersymmetric unparticles
We examine supersymmetric theories with approximately conformal sectors. Without an IR cutoff the theory has a continuum of modes, which are often referred to as ``unparticles.'' Making use of the

Unparticles-Higgs Interplay
We show that scalar unparticles coupled to the Standard Model Higgs at the renormalizable level can have a dramatic impact in the breaking of the electroweak symmetry already at tree level. In
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
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 study precision electroweak constraints within a RS1 model with gauge fields and fermions in the bulk. The electroweak gauge symmetry is enhanced to SU(2)L × SU(2)R × U(1)B−L, thereby providing a

Holographic unparticle Higgs boson
We propose an extra-dimensional approach to the unparticle Higgs. The nonlocal 4D unparticle Higgs action is derived as the boundary effective action of a local 5D theory. We review the mechanism to

We extend the 5D gauge-higgs scenario to the soft-wall framework where the IR brane is replaced by a smoothly decaying warp factor. The electroweak symmetry of the Standard Model is embedded in a
