我们证明了一个SU（2）L×U（1）Y模型，它具有与标准模型（SM）相同的粒子含量和第二代和第三代轻子之间的离散反射对称性，所产生的带电轻子和中微子质量矩阵可以容纳目前的太阳、大气和WMAP中微子实验结果.该模型预测了|U13|这可以在中微子工厂和有效马约拉纳中微子质量，这是在目前的实验值的低端进行测试。中微子质量是通过dim=5算子产生的，其尺度受的值限制。如果在未来的无中微子双β衰变实验（MOON，EXO，GENIUS）中，把这个下限移动一个数量级，那么由于LMA解的存在，目前的模型将不能容纳太阳中微子混合角。
We demonstrate that an SU(2)L×U(1)Y model with the same particle content as Standard Model (SM) and discrete reflection symmetry between second and third generations of leptons gives rise to charged lepton and neutrino mass matrices which can accommodate the present solar, atmospheric, WMAP neutrino experimental results. The model predicts the value of |U13| which could be tested in neutrino factories and the effective Majorana neutrino mass which is at the lower end of the present experimental value. Neutrino masses are generated through dim=5 operators and the scale of which are constrained by the value of . If, in future neutrinoless double beta decay experiments namely, MOON, EXO, GENIUS shift the lower bound on by one order, the present model will fail to accommodate the solar neutrino mixing angle due to LMA solution.
