TL;DR

This paper derives a neutrino mass matrix based on a cobimaximal mixing pattern, predicts neutrino masses and the effective Majorana mass, and discusses implications for future neutrinoless double beta decay experiments.

Contribution

It introduces a method to derive neutrino masses from a cobimaximal mixing matrix and evaluates predictions for neutrino masses and Majorana mass with texture zeros.

Findings

Neutrino masses are approximately 0.028, 0.029, and 0.058 eV.

Predicted effective Majorana mass is about 0.099 eV.

Results are testable in upcoming neutrinoless double beta decay experiments.

Abstract

Recently, we have a confidence that neutrino has a tiny mass and mixing does exist among neutrino flovors as one can see from experimental data that reported by many collaborations. Based on experimental data that flavor mixing does exist in neutrino sector which imply that all three mixing angles are nonzero, we derive the neutrino mass matrix from a cobimaximal neutrino mixing matrix. We also evaluate the prediction of neutrino mass matrix with texture zero from a cobimaximal neutrino mixing matrix on neutrino masses and effective Majorana mass. By using the advantages of experimental data, the obtained neutrino masses are $m_{1}=0.028188$ eV, $m_{2}=0.029488$ eV, and $m_{3}=0.057676$ eV, and the effective Majorana mass is $\left<m_{\beta\beta}\right>=0.09896$ eV that can be tested in future neutrinoless double beta decay experiments
