A4-Symmetric Double Seesaw for Neutrino Masses and Mixing
Analysis
Key Takeaways
- •Proposes a double seesaw model with A4 symmetry to explain neutrino masses and mixing.
- •Incorporates recent JUNO results to constrain the model's parameter space.
- •The model predicts a TBM structure with a single (1-3) rotation.
- •Offers a coherent explanation for neutrino masses and mixings and makes testable predictions.
“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.”
