In this work we have re-investigated two different kinds of texture zero ansatz of the low energy neutrino mass matrix in view of the Dark-Large-Mixing-Angle (DLMA) solution of the solar neutrino problem which can arise in the presence of non-standard interactions. In particular we revisit the cases of (i) one zero mass matrices when the lowest neutrino mass is zero and (ii) one zero texture with a vanishing minor. In our study we find that for most of the cases, the texture zero conditions which are allowed for the LMA solution, are also allowed for the DLMA solution. However, we found two textures belonging to the case of one zero texture with a vanishing minor where LMA solution does not give a viable solution whereas DLMA solution does. We analyze all the possible texture zero cases belonging to these two kinds of texture zero structures in detail and present correlations between different parameters. We also present the predictions for the effective neutrino mass governing neutrino-less double beta decay for the allowed textures.

在这项工作中，鉴于太阳中微子问题的暗大混合角 (DLMA) 解决方案，我们重新研究了低能中微子质量矩阵的两种不同的纹理零 ansatz。 - 标准互动。特别地，我们重新审视了以下情况：（i）当最低中微子质量为零时的零质量矩阵和（ii）具有消失次要的零纹理。在我们的研究中，我们发现在大多数情况下，LMA 解决方案所允许的纹理零条件也适用于 DLMA 解决方案。然而，我们发现两个纹理属于一个零纹理的情况，其中 LMA 解决方案不提供可行的解决方案，而 DLMA 解决方案提供。我们详细分析了属于这两种纹理零结构的所有可能的纹理零情况，并展示了不同参数之间的相关性。我们还提供了对有效中微子质量的预测，这些中微子质量控制了允许纹理的无中微子双 β 衰变。
