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 کاملCould the Supersymmetric Higgs Particles Naturally be Pseudo - Goldstone Bosons ?
The doublet-triplet splitting problem is perhaps the most problematic aspect of supersymmetric grand unified theories. It can be argued that the most natural reason for the Higgs doublets to be light is that they are pseudo-Goldstone bosons associated with the spontaneous breakdown of an accidental global symmetry. In this paper we discuss the possibility of implementing this idea in the SU(6) ...
متن کاملAre the Supersymmetric Higgs Particles Pseudo-goldstone Bosons?
A promising solution to the doublet-triplet splitting problem of SUSY GUT's is the Higgs as pseudo-Goldstone boson mechanism. We present two models which naturally implement this idea and extend one of them to include fermion masses. We examine the phenomenological consequences of this mechanism and present the favored parameter region. The perhaps most problematic aspect of SUSY GUT's is the d...
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.
متن کاملPseudo-Goldstone Higgs Production via Gluon Fusion
The gluon-gluon-higgs amplitude is investigated in the context of 5D models of gaugehiggs unification . A simple algorithm allows to include, in a fully analytical way, the contribution of the whole Kaluza-Klein tower of a 5D quark to the amplitude. This algorithm is applied to realistic models based on SO(5) symmetry. Within the studied classes of models, the higgs production cross section is ...
