Higgs as a Holographic Pseudo-Goldstone Boson
The AdS/CFT correspondence allows to relate 4D strongly coupled theories to weakly coupled theories in 5D AdS. We use this correspondence to study a scenario in which the Higgs appears as a composite pseudo-Goldstone boson (PGB) of a strongly coupled theory. We show how a non-linearly realized global symmetry protects the Higgs mass and guarantees the absence of quadratic divergences at any loo...
متن کاملHolographic pseudo-Goldstone boson
The LHC experiment will soon probe how W and Z bosons acquire their masses. So far we have only indirect hints about the actual mechanism of electroweak symmetry breaking. The standard model (SM) introduces a weakly coupled fundamental scalar field—the Higgs field— whose condensation breaks the electroweak symmetry. This simple picture is consistent with precision electroweak measurements, if t...
متن کاملAbout the holographic pseudo-Goldstone boson
Pseudo-Goldstone bosons in 4D strongly coupled theories have a dual description in terms of 5D gauge theories in warped backgrounds. We introduce systematic methods of computing the pseudo-Goldstone potential for an arbitrary warp factor in 5D. When applied to electroweak symmetry breaking, our approach clarifies the relation of physical observables to geometrical quantities in five dimensions....
متن کاملElectroweak Higgs as a pseudo-Goldstone boson of broken scale invariance
We point out that it is possible to associate the electroweak Higgs boson with the pseudoGoldstone boson of broken scale invariance, thus resolving the hierarchy problem in a technically natural way. We illustrate this idea with two specific gauge models. Besides being consistent with all currently available experimental data, both models maintain the predictive power of the standard model, sin...
متن کاملExotic Goldstone Particles: Pseudo-Goldstone Boson and Goldstone Fermion
This essay describes two exotic Goldstone particles. One is the pseudoGoldstone boson which is related to spontaneous breaking of an approximate symmetry. The other is the Goldstone fermion which is a natural result of spontaneously broken global supersymmetry. Their realization and implication in high energy physics are examined.
