The standard SU(3) S SU(2) S U(1) model provides a very successful description of the strong, weak, and electromagnetic interactions. It is, however, in no sense a fundamental theory. The SU(3) II SU(2) S U(1) model contains at least eighteen parameters, each of which must be adjusted by hand to account for low-energy phenomenology. What lies beyond the standard model? A variety of extensions h...

We study the dynamical symmetry breaking in the gauge-Higgs unification of the 5D N = 1 SUSY theory, compactified on an orbifold, S/Z2. This theory identifies Wilson line degrees of freedoms as “Higgs doublets”. We consider SU(3)c × SU(3)W and SU(6) models, in which the gauge symmetries are reduced to SU(3)c×SU(2)L×U(1)Y and SU(3)c×SU(2)L×U(1)Y ×U(1), respectively, through the orbifolding bound...

We show that any solution of the SU(2) Skyrme model can be used to give a topologically trivial solution of the SU(4) one. In addition, we extend the method introduced in [1] and use harmonic maps from S to CP (N−1) to construct low energy configurations of the SU(N) Skyrme models. We show that one of such maps gives an exact, topologically trivial, solution of the SU(3) model. We study various...

We study the vacuum structure and dynamical symmetry breaking in the gaugeHiggs unification of the 5D theory compactified on an orbifold, S/Z2. This theory identifies Wilson line degrees of freedoms as “Higgs doublets”. We consider SU(3)c × SU(3)W and SU(6) models with the compactification scale of order a few TeV. The gauge symmetries are reduced to SU(3)c × SU(2)L × U(1)Y and SU(3)c × SU(2)L ...

We propose a new model for describing baryon semi-leptonic decays for estimating F and D values with explicit breaking effects of both SU(3) and SU(2) flavor symmetry, where all possible SU(3) and SU(2) breaking effects are induced from an effective interaction. An overall fit including the weak magnetism form factor yields F = 0.477 ± 0.001, D = 0.835 ± 0.001, Vud = 0.975± 0.002, and Vus = 0.2...

We argue that the recently discovered integrability in the large-N CFT/AdS system is equivalent to diffractionless scattering of the corresponding hidden elementary excitations. This suggests that, perhaps, the key tool for finding the spectrum of this system is neither the gauge theory’s dilatation operator nor the string sigma model’s quantum Hamiltonian, but instead the respective factorized...
