“…The group ∆(27) was originally proposed to explain the fermion masses and flavor mixing in refs. [53,54], and has been used for Dirac neutrinos in [55] by one of us. Here we study its implementation in a warped extra dimensional theory.…”

A realistic five-dimensional warped scenario with all standard model fields propagating in the bulk is proposed. Mass hierarchies would in principle be accounted for by judicious choices of the bulk mass parameters, while fermion mixing angles are restricted by a ∆(27) flavor symmetry broken on the branes by flavon fields.The latter gives stringent predictions for the neutrino mixing parameters, and the Dirac CP violation phase, all described in terms of only two independent parameters at leading order. The scheme also gives an adequate CKM fit and should be testable within upcoming oscillation experiments.

“…Branco et al [27] proposed Z 3 symmetry among leptons and quarks, and introduced heavy right-handed Dirac and Majorana neutrinos for deriving light neutrinos in quark sectors and lepton sectors via the so-called seesaw mechanism [8]. Aranda et al [28] discussed that in order to create neutrino masses in a system with the Z 3 symmetry, neutrinos should be Dirac neutrinos instead of Majorana neutrinos.…”

We apply the Cartan's supersymmetric model to the weak interaction of hadrons.The electromagnetic currents are transformed by G 12 , G 123 , G 13 , G 132 and the factor(1− γ 5 ) is inserted between lν orlν when the photon is replaced by W ± , and between ll or νν when the photon is replaced by Z. We adopt Dirac lepton neutrinos and Majorana quark neutrinos, and construct a model that satisfy the Z 3 symmetry of the lepton sector and the quark sector, by adding two right-handed neutrinos whose left-handed partner cannot be detected by our electro-magnetic detectors. *

“…If, instead, L,Ē and N were all assigned unit R-charges, an additional discrete or flavor symmetry would be necessary to forbid lepton violation in the IR. Examples of such constructions can be found in [4][5][6] and [27].…”

Supersymmetric (SUSY) models with R-parity generically predict sparticle decays with invisible neutralinos, which yield distinctive missing energy events at colliders. Since most LHC searches are designed with this expectation, the putative bounds on sparticle masses become considerably weaker if R-parity is violated so that squarks and gluinos decay to jets with large QCD backgrounds. Here we introduce a scenario in which baryonic R-parity violation (RPV) arises effectively from soft SUSY breaking interactions, but leptonic RPV remains accidentally forbidden to evade constraints from proton decay and FCNCs. The model features a global R-symmetry that initially forbids RPV interactions, a hidden R-breaking sector, and a heavy mediator that communicates this breaking to the visible sector. After R-symmetry breaking, the mediator is integrated out and an effective RPV A-term arises at tree level; RPV couplings between quarks and squarks arise only at loop level and receive additional suppression. Although this mediator must be heavy compared to soft masses, the model introduces no new hierarchy since viable RPV can arise when the mediator mass is near the SUSY breaking scale. In generic regions of parameter space, a light thermally-produced gravitino is stable and can be a viable dark matter candidate.
