A Viable Flavor Model for Quarks and Leptons in RS with T' Family Symmetry

We propose a Randall‐Sundrum model with a bulk family symmetry based on the double tetrahedral group, T′, which generates the tri‐bimaximal neutrino mixing pattern and a realistic CKM matrix. The T′ symmetry forbids tree‐level flavor‐changing‐neutral‐currents in both the quark and lepton sectors, as different generations of fermions are unified into multiplets of T′. This results in a low first KK mass scale and thus the model can be tested at collider experiments.
