Title: UV completions of flavour models and large θ 13
Abstract: The ultraviolet completion of flavour models can strongly improve the predictivity of the respective effective models. We consider A 4 models, existing minimal UV completions and construct several next-to-minimal UV complete models. We compare the results of these possibilities to the experimental data including θ 13. Through the predictive power of the UV completions, we are able to either rule out or constrain several minimal and next-to-minimal alternatives.
