本文提出了一个超对称模型，它的味对称性和CP对称性在带电轻子扇区中破缺为味对称性的一个子群，在中微子扇区中破缺为CP（）。该模型实现了一种方法，能够预测轻子混合角和狄拉克以及马约拉纳阶段的一个自由参数。该参数直接与反应器混合角的大小相关，在我们的模型中可以自然地具有正确的顺序。大气混合是最大的，而。所有三个阶段的预测：狄拉克阶段是最大的，而两个马约拉纳阶段是平凡的。中微子的质量矩阵只包含三个真实的参数在领先的顺序和中微子的质量有效地只取决于其中的两个。因此，它们必须是正常有序的，并且绝对中微子质量标度和中微子质量之和被预测。可以正确地对准黄酮的真空。我们研究子领导的修正领先的顺序的结果，并表明，他们是小的。
We present a supersymmetric model with the flavour symmetryand a CP symmetry which are broken to asubgroup of the flavour symmetry in the charged lepton sector and toCP () in the neutrino one at leading order. This model implements an approach capable of predicting lepton mixing angles and Dirac as well as Majorana phases in terms of one free parameter. This parameter, directly related to the size of the reactor mixing angle, can be naturally of the correct order in our model. Atmospheric mixing is maximal, while. All three phases are predicted: the Dirac phase is maximal, whereas the two Majorana phases are trivial. The neutrino mass matrix contains only three real parameters at leading order and neutrino masses effectively only depend on two of them. As a consequence, they have to be normally ordered and the absolute neutrino mass scale and the sum of the neutrino masses are predicted. The vacuum of the flavons can be correctly aligned. We study subleading corrections to the leading order results and show that they are small.
