TLDR
In this article, it was shown that the electroweak symmetry can be broken by boundary conditions, leading to a new type of Higgsless theories in 5 dimensions, which could in principle improve on the 4D case by extending the perturbative domain to energies higher than 4πv.About:

The Minimal Composite Higgs Model
TL;DR: In this article, the authors proposed a composite Higgs in the framework of a five-dimensional AdS theory, where electroweak symmetry is broken dynamically via top loop effects, all flavour problems are solved, and contributions to electroweak precision observables are below experimental bounds.
Journal ArticleDOI
The Strongly-Interacting Light Higgs
TL;DR: In this paper, the authors developed 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.

Chiral symmetry breaking from five-dimensional spaces
Leandro Da Rold,Alex Pomarol +1 more
TL;DR: In this article, the breaking of the chiral symmetry in QCD using a simple five-dimensional model was studied based on the AdS/CFT correspondence and the model gave definite predictions for the spectrum of vector mesons, their decay constants and interactions as a function of one parameter related to the quark condensate.

A custodial symmetry for Zbb
TL;DR: In this article, a subgroup of the custodial symmetry O(3) that protects ρ from radiative corrections can also protect the ZbRR coupling, which allows one to build models of electroweak symmetry breaking, such as Higgsless, Little Higgs or 5D composite Higgs models, that are safe from corrections to Z → bb.

Light composite Higgs boson from higher representations versus electroweak precision measurements: Predictions for CERN LHC
TL;DR: In this article, the authors investigate theories in which the technifermions in higher dimensional representations of the technicolor gauge group dynamically break the electroweak symmetry of the standard model.

Michael E. Peskin,Tatsu Takeuchi +1 more
TL;DR: The experimental limits placed on the oblique correction parameters S and T are reviewed and the value of S can be estimated for running and walking technicolor theories are discussed.

Chiral quarks and the non-relativistic quark model
Aneesh Manohar,Howard Georgi +1 more
TL;DR: In this paper, the consequences of an effective lagrangian for quarks, gluons and goldstone bosons in the region between the chiral symmetry breaking and confinement scales were studied.

New constraint on a strongly interacting Higgs sector
Michael E. Peskin,Tatsu Takeuchi +1 more
TL;DR: It is shown that an integral {ital S} over the spectral function of spin-1 states of the Higgs sector is constrained by precision weak-interaction measurements.
Journal ArticleDOI
Precise Relations between the Spectra of Vector and Axial-Vector Mesons
TL;DR: In this paper, the moments of the spectral functions of the vector and axial vector currents were derived, and two sum rules were derived for relating moments of spectral functions, and it was shown that if it is assumed that the $\ensuremath{\rho}$ and $A1$ mesons dominate these moments, then their masses must be in the ratio

Strong Interactions and Stability in the DGP Model
TL;DR: The model of Dvali, Gabadadze and Porrati (DGP) as mentioned in this paper gives a simple geometrical setup in which gravity becomes 5-dimensional at distances larger than a length scale lambda(DGP).
