Analysis

This paper proposes a model for neutrino masses and mixing using a double seesaw mechanism and A4 flavor symmetry. It's significant because it attempts to explain neutrino properties within the Standard Model, incorporating recent experimental results from JUNO. The model's predictiveness and testability are highlighted.

Reference

The paper highlights that the combination of the double seesaw mechanism and A4 flavour alignments yields a leading-order TBM structure, corrected by a single rotation in the (1-3) sector.
