TL;DR: In this paper, the Higgs boson is a pseudo-Nambu-Goldstone boson and the potential contains a Higgs quartic coupling which does not introduce one-loop quadratic divergences.
Abstract: We present a model of electroweak symmetry breaking in which the Higgs boson is a pseudo-Nambu-Goldstone boson. By embedding the standard models SU(2) × U(1) into an SU(4) × U(1) gauge group, one-loop quadratic divergences to the Higgs mass from gauge and top loops are canceled automatically with the minimal particle content. The potential contains a Higgs quartic coupling which does not introduce one-loop quadratic divergences. Our theory is weakly coupled at the electroweak scale, it has new weakly coupled particles at the TeV scale and a cutoff above 10 TeV, all without fine tuning. We discuss the spectrum of the model and estimate the constraints from electroweak precision measurements.

TL;DR: The physics potential of linear linear colliders has been discussed in this paper, where the authors describe the potential for the discovery of particles in supersymmetric extensions of the Standard Model, the spectrum of Higgs particles, the super-ymmetric partners of the electroweak gauge and Higgs bosons.

TL;DR: In this paper, a new mechanism through which a net baryon asymmetry could be generated at the electroweak phase transition is discussed, which works efficiently in minimal extensions of the standard model such as occur in supersymmetric theories, where the Higgs sector involves more than one doublet.

TL;DR: In this article, the background-field Green functions are shown to possess very desirable theoretical properties and a consistent on-shell renormalization procedure retaining the full gauge symmetry is presented.

TL;DR: In this paper, it was shown that QCD originates in the chiral color group SU(3)×SU(3), and that the scale of chiral-color breaking is similar to the electroweak mass scale.
