Empirical Neutrino Mass Matrix Related to Up-Quark Masses

TL;DR

This paper proposes an empirical neutrino mass matrix model linked to up-quark and charged lepton masses, explaining neutrino mixing patterns, especially near tribimaximal mixing, within a flavor scalar framework.

Contribution

It introduces a novel empirical neutrino mass matrix derived from quark and lepton mass spectra based on flavor scalar vacuum expectation values.

Findings

Neutrino mass matrix can reproduce nearly tribimaximal mixing

Model connects neutrino masses to up-quark and charged lepton masses

Supports flavor scalar approach for mass generation

Abstract

Based on an approach to quark and lepton masses, where the mass spectra originate in vacuum expectation values of U(3) flavor nonet (gauge singlet) scalars, neutrino masses and mixing are investigated. As an offshoot of this approach, it is found that an empirical neutrino mass matrix which is described in terms of the up-quark and charged lepton masses can accommodate to a nearly tribimaximal mixing.
