论文摘要
我们研究了Majorana光中微子质量矩阵中质地零的可能性，该质子质基质是根据深度混合角（DLMA）解决方案来解决太阳中微子问题的可能性，其中太阳能混合角（$ \ sin^2 {θ_{θ_{12}}}} \ simeq 0.7 $）在第二个彩色八个八个八个八个八个八个八个八月中，而不是标准大型混合角度（lma）。 （$ \ sin^2 {θ_{12}} \ simeq 0.3 $）。在三种中微子方案中，我们发现LMA和DLMA解决方案带来了不同的和两个零的允许和不允许的纹理。尽管与中微子振荡数据的现有界限保持一致，但中微子双β衰变和宇宙学允许纹理也导致光中微子参数之间有趣的相关性，这些参数可以将LMA与DLMA溶液区分开。我们还使用LMA和DLMA解决方案检查了$ 3+1 $中微子方案的纹理零的含义。尽管在这种情况下，LMA和DLMA解决方案在排除纹理零方面并不发挥决定性的作用，但它们确实会产生明显的预测和光中微子参数之间的相关性。
We study the possibility of texture zeros in Majorana light neutrino mass matrix in the light of dark large mixing angle (DLMA) solution to solar neutrino problem where solar mixing angle ($\sin^2{θ_{12}}\simeq 0.7 $) lies in the second octant instead of first octant in standard large mixing angle (LMA) scenario ($\sin^2{θ_{12}}\simeq 0.3 $). In three neutrino scenario, we find that LMA and DLMA solutions lead to different set of allowed and disallowed textures with one and two zeros. While being consistent with existing bounds from neutrino oscillation data, neutrinoless double beta decay and cosmology these allowed textures also lead to interesting correlations among light neutrino parameters which can distinguish LMA from DLMA solution. We also check the implications for texture zeros in $3+1$ neutrino scenario using both LMA and DLMA solutions. While LMA and DLMA solutions do not play decisive role in ruling out texture zeros in this case, they do give rise to distinct predictions and correlations between light neutrino parameters.
