论文摘要
长期以来，已经研究了三型二体 - 最大模式为中微子混合矩阵背后的对称情况。它预测了Lepton部门中违反$ CP $ cp $的无效反应器角度，这与当前的实验确定形成了鲜明对比。我们探索与这种模式的不同偏差，以恢复与最新中微子混合参数的兼容性。我们考虑两个统一矩阵以纠正对称模式，每个矩阵都是用一个角度和一个复杂阶段编写的，这将受到实验混合和质量矩阵中的对称限制的约束。我们注意到，这些校正参数将使我们能够在某些特定情况下获得有关Dirac和Majoraana $ CP $阶段的同时信息。我们表明，预测的值导致了中微子双β衰减幅度的共享区域，在选定的情况下，可以通过即将到来的结果进行测试。
The Tri-Bi-Maximal pattern has been long investigated as the symmetric scenario that lies behind the neutrino mixing matrix. It predicts a null reactor angle and hence forbids $CP$ violation in the lepton sector, which is in contrast to the current experimental determinations. We explore different deviations from this pattern to restore the compatibility with the latest fits of neutrino mixing parameters. We consider two unitary matrices to correct the symmetric pattern, each of them is written in terms of one single angle and one complex phase, which will be constrained by the experimental mixings and from symmetry restrictions in the mass matrix. We note that these correction parameters would allow us to obtain simultaneous information about the Dirac and Majorana $CP$ phases in some specific scenarios. We show that the predicted values lead to sharped regions for the neutrinoless double beta decay amplitude, in the selected cases, that could be tested with forthcoming results.
