Novel Randall-Sundrum model with S3 flavor symmetry

We propose a simple and predictive model of fermion masses and mixing in a warped extra dimension, with the smallest discrete non-Abelian group S3 and the discrete symmetries Z2 - Z4. Standard Model fields propagate in the bulk, and the mass hierarchies and mixing angles are accounted for the fermion zero modes localization profiles, similar to the Randall-Sundrum model. To the best of our knowledge, this model is the first implementation of an S3 flavor symmetry in this type of warped extra dimension framework. Our model successfully describes the fermion masses and mixing pattern and is consistent with the current low energy fermion flavor data. The discrete flavor symmetry in our model leads to predictive mixing inspired textures, where the Cabibbo mixing arises from the down-type quark sector, whereas the up-type quark sector contributes to the remaining mixing angles.
