Scaling in the minimal extended seesaw model

TL;DR

This paper explores scaling relations in neutrino mass matrices within the minimal extended seesaw model, showing some relations hold without the need for two zero elements, expanding understanding of neutrino mass textures.

Contribution

It demonstrates that certain scaling relations in neutrino mass matrices can be satisfied without the two-zero texture requirement, broadening the scope of the minimal extended seesaw model.

Findings

Some scaling relations are valid without two-zero textures

Expansion of the minimal extended seesaw model's applicability

Potential implications for neutrino mass model building

Abstract

The scaling relations in the two-zero textures of the neutrino mass matrices in the minimal extended seesaw mechanism were discovered by Kumar and Patgiri. We demonstrate that some of these scaling relations can be satisfied without requiring two zero elements in the texture.
