UV completions of A4 models with viable theta13
The ultraviolet completion of flavour models can strongly improve the predictivity of the respective effective models. We consider A4 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 theta13. Through the predictive power of the UV completions, we are able to either rule out or constrain several minimal and next-to-minimal alternatives.
