In this work, we propose new five texture zeros for the mass matrices in the lepton sector in order to predict neutrino masses. In our approach, we extend beyond the standard model (SM) by assuming Dirac masses for the neutrinos, a feature which allows us to make a theoretical prediction for the lightest neutrino mass in the normal ordering. The textures that were analyzed have enough free parameters to adjust the V PMNS mixing matrix including the CP-violating phase, the neutrino mass squared differences ##IMG## [http://ej.iop.org/images/0954-3899/47/11/115002/gabb029ieqn1.gif] {$\delta {m}_{21}^{2},\delta {m}_{31}^{2}$} , and the three charged lepton masses. In order to obtain reliable results, we used two different procedures that are based on the weak basis transformation, a well known technique to analyze textures and their implications for flavor physics. The first method was based on a least-squares analysis to theoretically fit the ...

狄拉克中微子质量矩阵的五个纹理零

在这项工作中,我们为轻子领域的质量矩阵提出了新的五个纹理零点,以预测中微子的质量。在我们的方法中,我们通过假设中微子的狄拉克质量,超越了标准模型(SM),这一功能使我们能够对正常次序中最轻的中微子质量做出理论上的预测。分析的纹理具有足够的自由参数来调整V PMNS混合矩阵,包括违反CP的相位,中微子质量平方差## IMG ## [http://ej.iop.org/images/0954-3899/ 47/11/115002 / gabb029ieqn1.gif] {$ \ delta {m} _ {21} ^ {2},\ delta {m} _ {31} ^ {2} $}和三个带电的轻子质量。为了获得可靠的结果,我们使用了两种基于弱基变换的不同过程,一种分析质地及其对风味物理的影响的著名技术。第一种方法基于最小二乘分析,以理论上拟合...
