摘要

我们提出了一种独特的轻子混合方案，并根据离散味道对称框架下的I型+II型跷跷板机制，将其与精确的层次-亲和性中微子质量矩阵纹理联系起来。所提出的模型成功地预测了中微子质量的正常排序和两个马约拉纳相。此外，分析还扩展到了无中微子双贝塔背景下的有效马约拉纳中微子质量。

A realistic neutrino mixing scheme arising from A4 symmetry

We propose a unique lepton mixing scheme and its association with an exact hierarchy-philic neutrino mass matrix texture in the light of Type-I+Type-II seesaw mechanism under the framework of discrete flavour symmetry. The proposed model successfully predicts the normal ordering of neutrino masses and the two Majorana phases. Additionally, the analysis extends to the effective Majorana neutrino mass, in the context of neutrinoless double beta .

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
