Zee Neutrino Mass Matrix in the Gauge Mediated Supersymmetry Breaking Scenario

TL;DR

This paper explores how the Zee neutrino mass matrix can be realized within gauge mediated supersymmetry breaking, naturally producing tiny neutrino masses and large lepton mixings consistent with experimental data.

Contribution

It demonstrates a mechanism for generating the Zee neutrino mass matrix in gauge mediated supersymmetry breaking with suitable B-L charges, aligning with neutrino oscillation observations.

Findings

Neutrino masses are naturally tiny due to radiative corrections.

Large lepton flavor mixing is achieved in the model.

Results are consistent with three and four neutrino oscillation data.

Abstract

It is well known that Zee type neutrino mass matrix can provide bi-maximal neutrino mixing for three neutrinos. We study the reconciliation of this model with the gauge mediated supersymmetry breaking scenario, which naturally suppresses the large flavor changing neutral current and CP violation in the supersymmetric standard model. When the messenger fields have suitable B-L charges, the radiative correction naturally induces the Zee neutrino mass matrix, which provides tiny neutrino masses and large lepton flavor mixings. Our numerical results are consistent with the neutrino oscillation experiments in both three and four neutrino models.
