TL;DR

This paper introduces a novel radiative seesaw model with higher order operators under an alternative $U(1)_{B-L}$ symmetry, explaining neutrino masses, dark matter, and lepton flavor violations while fitting current experimental data.

Contribution

It presents a new model incorporating 5-dimensional operators in an alternative $U(1)_{B-L}$ framework, addressing neutrino masses, dark matter, and cosmological constraints.

Findings

Identifies parameter regions consistent with neutrino oscillation data.

Demonstrates compatibility with dark matter stability and neutrino species constraints.

Analyzes lepton flavor violation processes within the model.

Abstract

We propose a model based on an alternative $U(1)_{B-L}$ gauge symmetry with 5 dimensional operators in the Lagrangian, and we construct the neutrino masses at one-loop level, and discuss lepton flavor violations, dark matter, and the effective number of neutrino species due to two massless particles in our model. Then we search allowed region to satisfy the current experimental data of neutrino oscillation and lepton flavor violations without conflict of several constraints such as stability of dark matter and the effective number of neutrino species, depending on normal hierarchy and inverted one.
