Texture zeros flavor neutrino mass matrix and triplet Higgs models

TL;DR

This paper explores how specific texture zeros in the neutrino mass matrix, combined with the type-II seesaw mechanism in triplet Higgs models, can naturally explain observed neutrino mixing and tiny masses.

Contribution

It identifies a particularly natural one-zero texture case compatible with observations within the triplet Higgs model framework.

Findings

One-zero texture case aligns well with experimental data.

Type-II seesaw mechanism explains tiny neutrino masses.

Certain texture zeros are favored in triplet Higgs models.

Abstract

One- and two-zero textures for the flavor neutrino mass matrix have been successful in explaining mixing in the neutrino sector. Conservatively, six cases of one-zero textures and seven cases of two-zero textures are compatible with observations. We show that one case may be the most natural in the one- and two-zero textures schemes if tiny neutrino masses are generated by the type-II seesaw mechanism in triplet Higgs models.
