TL;DR: In this paper, a new approach to study models of fermion masses and mixings, namely, the anarchy proposed by Hall, Murayama, and Weiner, was proposed.

TL;DR: In this paper, a model of direct gauge mediation of metastable supersymmetry breaking by simply deforming the Intriligator, Seiberg, and Shih model in terms of a dual meson superpotential mass term is presented.

Abstract: We study the dynamical symmetry breaking in the gauge-Higgs unification of the five-dimensional theory compactified on an orbifold, ${S}^{1}{/Z}_{2}.$ This theory identifies Wilson line degrees of freedom as ``Higgs doublets.'' We consider ${\mathrm{SU}(3)}_{c}\ifmmode\times\else\texttimes\fi{}{\mathrm{SU}(3)}_{W}$ and $\mathrm{SU}(6)$ models with the compactification scale of order of a few TeV. The gauge symmetries are reduced to ${\mathrm{SU}(3)}_{c}\ifmmode\times\else\texttimes\fi{}{\mathrm{SU}(2)}_{L}\ifmmode\times\else\texttimes\fi{}{U(1)}_{Y}$ and ${\mathrm{SU}(3)}_{c}\ifmmode\times\else\texttimes\fi{}{\mathrm{SU}(2)}_{L}\ifmmode\times\else\texttimes\fi{}{U(1)}_{Y}\ifmmode\times\else\texttimes\fi{}U(1),$ respectively, through the orbifolding boundary conditions. We estimate the one loop effective potential of ``Higgs doublets,'' and find that the electroweak breaking is realized through the radiative corrections when there are suitable numbers of bulk fields possessing the suitable representations. The masses of ``Higgs doublets'' are O(100) GeV in this scenario.

TL;DR: A new framework for handling flavor symmetry breaking in the neutrino sector is discussed where the source of symmetry breaking is traced to the global property of right-handed neutrinos in extra-dimensional space.

TL;DR: In this paper, a reverse pathway of the asymmetric dark matter scenario is proposed to generate a suitable baryon asymmetry from the hidden sector, and the asymmetry of dark matter is partially transferred into the standard model sector.
