New magic textures of Majorana neutrinos and baryon asymmetry of the Universe

TL;DR

This paper introduces two new types of magic textures for Majorana neutrino mass matrices, consistent with experimental data, and explores their implications for leptogenesis and the universe's baryon asymmetry.

Contribution

It proposes novel magic textures for Majorana neutrinos and links them to leptogenesis, expanding understanding of neutrino mass models and baryon asymmetry.

Findings

Two new magic textures are compatible with experimental data.

The new textures can explain the baryon asymmetry via leptogenesis.

The textures align with neutrino oscillation and cosmological observations.

Abstract

The magic texture is one of the successful textures of the flavor neutrino mass matrix for Majorana neutrinos. In this paper, it turns out that two new types of magic textures are also consistent with the neutrino oscillation experiments, observation of cosmic microwave background radiation, and neutrinoless double beta decay experiments. The connection between these new magic textures and the leptogenesis scenario of the origin of the baryon asymmetry of the Universe is also discussed.
