MPPL Lecture 2 – Who ordered that? Probing neutrino flavor models with precision neutrino experiments

The observed flavor pattern of neutrinos, their large mixings and the smallness of their masses compared to the masses of the other fermions provides a great puzzle. In this talk I will review explanations to this puzzle based on symmetries and then focus on the predictions and testability of these flavor models. I will put a particular focus on the most predictive class of models which relate different observables with each other.

I will show how upcoming neutrino experiments like oscillation experiments, neutrinoless double beta decay experiments, and cosmological observatories can probe and differentiate between different flavor models and therefore provide more insights into the flavor puzzle of the Standard Model.
