观测到的中微子质量和混合模式为超出标准模型的物理提供了有力证据，这进一步推动了对可预测框架的探索，该框架能同时解决味结构及其现象学后果。本研究特别在具有A₄模对称的通用左右对称模型中，研究所有7种可能的双零中微子质量纹理的实现。通过考虑模权重4、8和10，我们系统地构建了所有可能类别的双零纹理，且未引入任何 flavon 场，这增强了框架的预测能力。本研究还确定了能同时适配当前中微子数据、重现观测到的重子不对称性，并为无中微子双β衰变的新物理贡献给出有效马约拉纳中微子质量的实验可测试结果的纹理类。
英文摘要
The observed pattern for neutrino masses and mixing provides compelling evidence for Beyond Standard Model physics which further motivates the search for predictive frameworks that can simultaneously address flavor structure and its phenomenological consequences. This work particularly investigates the realization of all possible seven two-zero neutrino mass textures within the generic left-right symmetric model with $A_{4}$ modular symmetry. By considering modular weights 4,8 and 10, we systematically construct all the possible classes of 2-0 textures without the introduction of any flavon fields which enhances the predictive power of the framework. In this work, we also identify the texture classes capable of simultaneously accommodating current neutrino data, reproducing the observed baryon asymmetry and also yielding experimentally testable results for the effective Majorana neutrino mass for new physics contributions of neutrinoless double beta decay.
