Scotogenic dark matter and single-zero textures of the neutrino mass matrix

TL;DR

This paper investigates a specific neutrino mass matrix pattern within the scotogenic model, demonstrating its compatibility with neutrino oscillation data, dark matter relic abundance, and experimental constraints.

Contribution

It identifies a unique viable one-zero-texture pattern of the neutrino mass matrix in the scotogenic model consistent with current observations.

Findings

Only one one-zero-texture pattern is viable.

The model aligns with neutrino oscillation data.

The dark matter relic abundance and $\, ext{BR}(\, ext{$ ext{μ} ightarrow e ext{γ}$} ext{)}$ constraints are satisfied.

Abstract

The scotogenic model can simultaneously account for the presence of dark matter and the origin of neutrino masses. We assume that the flavor neutrino mass matrix has one zero element and Yukawa matrix elements are real in the scotogenic model. It turns out that only one pattern of the flavor neutrino mass matrix in the one-zero-texture scheme within the scotogenic model is viable with the observed neutrino oscillation data, the relic abundance of the dark matter, and the upper limit of the branching ratio of the $\mu \rightarrow e \gamma$ process.
