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

Understand

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.
