Robustness of Neutrino Mass Matrix Predictions

Understand

We investigate the stability of neutrino mass matrix predictions on important and currently unknown observables.

• Those are the octant of $\theta_{23}$, the sign of $\sin\delta$ and the neutrino mass ordering.
• Determining those unknowns is expected to be useful in order to distinguish neutrino mass models.
• Therefore it may be interesting to know how robust the predictions of a mass matrix for the octant of $\theta_{23}$ or the neutrino mass ordering are.
