Based on the AdS/CFT correspondence we study the breaking of the chiral symmetry in QCD using a simple five dimensional model. The model gives definite predictions for the spectrum of vector mesons,… (More)

Five-dimensional models where the bulk is a slice of AdS have the virtue of solving the hierarchy problem. The electroweak scale is generated by a “warp” factor of the induced metric on the brane… (More)

We study the idea of a composite Higgs in the framework of a five-dimensional AdS theory. We present the minimal model of the Higgs as a pseudo-Goldstone boson in which electroweak symmetry is broken… (More)

We present a class of composite Higgs models arising from a warped extra dimension that can satisfy all the electroweak precision tests in a significant portion of their parameter space. A custodial… (More)

In a generic “universal” theory of electroweak symmetry breaking, simple symmetry considerations and absence of tuning imply that heavy new physics affects the lowenergy data through four parameters.… (More)

We develop a simple description of models where electroweak symmetry breaking is triggered by a light composite Higgs, which emerges from a strongly-interacting sector as a pseudo-Goldstone boson.… (More)

We show that a subgroup of the custodial symmetry O(3) that protects ∆ρ from radiative corrections can also protect the Zbb̄ coupling. This allows one to build models of electroweak symmetry… (More)

We study the implications of extra dimensions of size R ∼ 1/TeV on electroweak and flavor physics due to the presence of Kaluza-Klein excitations of the SM gauge-bosons. We consider several scenarios… (More)

We point out that the µ-problem in theories in which supersymmetry breaking is communicated to the observable sector by gauge interactions is more severe than the one encountered in the conventional… (More)

We discuss a recently proposed scenario where the sparticle masses are purely mediated by gravity through the superconformal anomaly. This scenario elegantly evades the supersymmetric flavor problem… (More)
