我们计算有限的量子修正的tribimmaximal中微子混合模式V TB在三个通用类的中微子质量模型。结果表明，三种味混合角都能偏离VTB描述的树级结果，其中θ 12对这种量子效应最为敏感，Dirac CP破坏相可以由两个Majorana CP破坏相辐射产生.这个理论方案提供了一种新的方法来理解为什么θ 13自然很小，以及三个CP破坏相位是如何相互关联的。
We calculate finite quantum corrections to the tribimaximal neutrino mixing pattern V TB in three generic classes of neutrino mass models. We show that three flavor mixing angles can all depart from their tree-level results described by V TB, among which θ 12 is most sensitive to such quantum effects, and the Dirac CP-violating phase can radiatively arise from two Majorana CP-violating phases. This theoretical scheme offers a new way to understand why θ 13 is naturally small and how three CP-violating phases are presumably correlated.
