“…Of course, different models give various spectra of particles with their own features each. Here, we would like to come back on a model we developed during the last decade and which proved fruitful to explain masses and mixing of both charged and neutral fermions [7,8,9,10] (in particular, we made predictions for the neutrino sector [9,10,11], relating Majorana character to large mixing and inverted hierarchy, and successfully predictingin tempore non suspecto -the last mixing angle θ 13 ). In this model, we add to our usual four-dimensional (4D) world, two ED with a Nielsen-Olesen vortex structure on it.…”

Abstract:We consider the phenomenology of new neutral gauge bosons with flavour nondiagonal couplings to fermions, inherent in 6D models explaining successfully the hierarchy of masses as well as the mixing for quarks, charged leptons and neutrinos (this model can in particular be credited with the correct prediction of the neutrino mixing angle θ 13 ). We present a general relation between masses of new gauge bosons and their couplings to fermions. We show that in the current realization of the model, the new heavy bosons are unreachable at LHC but argue why the constraint could be relaxed in the context of a different realization. In view of a more systematic study, we use an effective model inspired by the above to relate directly rare meson decays to possible LHC observations. In terms of effective Lagrangians, this can be seen as the introduction in the model of only one overall scaling parameter to extend our approach without modifying the 4D (gauge) structure.

“…For the sake of consistency, we will also try to take the "quasi-unitarity" suppression discussed in section 3 into account 9. We use the definition Q = T 3 + Y 10. This corrects the smaller values erroneously mentioned in[14].…”
