Two-loop Induced Majorana Neutrino Mass in a Radiatively Induced Quark and Lepton Mass Model

TL;DR

This paper proposes a two-loop radiative neutrino mass model extending previous work, addressing neutrino oscillations, lepton flavor violations, muon g-2, and dark matter, with numerical analysis fitting experimental data at TeV scales.

Contribution

It introduces a novel two-loop induced neutrino mass mechanism within a radiative model, incorporating fermion mass generation and dark matter candidate.

Findings

Less hierarchical Yukawa couplings can fit experimental data.

Model accommodates both normal and inverted neutrino mass hierarchies.

TeV scale dark matter is consistent with observations.

Abstract

A two-loop induced radiative neutrino model is proposed as an extension of our previous work in which the first and second generation standard model fermion masses are generated at one-loop level in both quark and lepton sectors. Then we discuss current neutrino oscillation data, lepton flavor violations, muon anomalous magnetic moment, and a bosonic dark matter candidate, for both the normal and inverted neutrino mass hierarchy. Our numerical analysis shows that less hierarchical Yukawa coupling constants can fit the experimental data with TeV scale dark matter.
