Description
In this work, we revisit the constraints on neutrinos flavour models given by discrete symmetries. We study the solar and atmospheric sum rules and test them against the up-to-date fit of the neutrino oscillation data. We show that some models, such as a version of the Golden Ratio (GR1), are already excluded at $3\sigma$ and discuss which are the most favored models by the data. We also test Littlest Seesaw models, which can be considered a subset of one class of tri-maximal mixing models (TM1), we show their high predictivity and present their constraints.
