论文摘要
在这项工作中,我们假设了Lepton部门的带电和中性质量矩阵的特殊结构,灵感来自于在其条目中假设一定数量的对称零零来导致的Quark质量矩阵的结构。 Lepton混合矩阵的预测是由中性和带电的Lepton扇区中的质量矩阵对角线的旋转矩阵产生的。纹理零的使用将虚假参数的数量减少到解释观察值所需的最小值参数,即带电的Lepton群众和中微子振荡参数。具体而言,我们考虑了五个纹理零的情况,并且我们已经面对了中微子部门的当前测量结果的Lepton混合矩阵。最后,使用模拟事件在沙丘中微子振荡实验中研究了对非效法形式预测的混合中的独立参数的敏感性。我们发现,沙丘对模型中允许的非零CP违规敏感。
In this work, we have assumed special structures for the charged and neutral mass matrices in the lepton sector, inspired by structures for the up and down quark mass matrices that result by assuming a certain number of symmetrical zeros in their entries named texture zeros. A prediction of the lepton mixing matrix results from the rotation matrices that diagonalize the mass matrices in the neutral and charged lepton sectors. The use of texture zeros reduces the number of spurious parameters to the minimal ones needed to explain observations i.e. charged lepton masses and neutrino oscillation parameters. Specifically, we have considered the case of five texture zeros and we have confronted the resulting lepton mixing matrices with current measurements in the neutrino sector. Finally, sensitivities to the independent parameters in the mixing predicted by the nonequivalent forms were studied using simulated events at the DUNE neutrino oscillation experiment. We have found that DUNE is sensitive to nonzero CP violation allowed in the models.
