Nonlinear realization and hidden local symmetries

M Bando, T Kugo, K Yamawaki - Physics Reports, 1988 - Elsevier
The idea of dynamical gauge bosons of hidden local symmetries in nonlinear sigma models
is reviewed. Starting with a fresh look at the Goldstone theorem and low energy theorems …

[PDF][PDF] Beyond the standard model with six-dimensional spacetime

D Chester, A Marrani, M Rios - arXiv preprint arXiv:2002.02391, 2020 - academia.edu
6D spacetime with SO (3, 3) symmetry is utilized to efficiently encode three generations of
matter. A graviGUT model is generalized to a class of models that all contain three …

Bulk and brane anomalies in six dimensions

T Asaka, W Buchmüller, L Covi - Nuclear Physics B, 2003 - Elsevier
We study anomalies of six-dimensional gauge theories compactified on orbifolds. In addition
to the known bulk anomalies, brane anomalies appear on orbifold fixpoints in the case of …

F-theory family unification

S Mizoguchi - Journal of High Energy Physics, 2014 - Springer
A bstract We propose a new geometric mechanism for naturally realizing unparallel three
families of flavors in string theory, using the framework of F-theory. We consider a set of …

Family unification in five and six dimensions

KS Babu, SM Barr, B Kyae - Physical Review D, 2002 - APS
In family unification models, all three families of quarks and leptons are grouped together
into an irreducible representation of a simple gauge group, thus unifying the standard model …

Flavour-changing Z0 decays

W Buchmüller, M Gronau - Physics Letters B, 1989 - Elsevier
We compute neutral Higgs and Z0-boson couplings to quarks in a model with three quark-
lepton families and one mirror family. Mixing between ordinary and mirrorquarks leads to …

Beyond the standard model with six-dimensional spinors

D Chester, A Marrani, M Rios - Particles, 2023 - mdpi.com
Six-dimensional spinors with S pin (3, 3) symmetry are utilized to efficiently encode three
generations of matter. E 8 (− 24) is shown to contain physically relevant subgroups with …

Exceptional coset spaces and unification in six dimensions

T Asaka, W Buchmüller, L Covi - Physics Letters B, 2002 - Elsevier
The coset spaces E8/SO (10)× HF allow complex structures which can account for three
quark–lepton generations including right-handed neutrinos. We show that in the context of …
