我们证明了在引入Frampton-Yanghow-Yanagida（FGY）模型的最小跷跷板模型中，所有的非平凡CP破坏相位都可以用三个轻子味混合角和Δ m2 sun与Δ m2 at的比值来确定.这一点使我们能够对宇宙学重子数不对称性和中微子振荡中的CP破坏做出非常具体的预测。最小中微子混合角的测量将灵敏地检验FGY的测量，特别是在三个轻中微子具有正常质量等级的情况下。
We show that all nontrivial CP-violating phases can be determined in terms of three lepton flavor mixing angles and the ratio of Δm2sunto Δm2atmin the minimal seesaw model in which the Frampton–Glashow–Yanagida (FGY) ansatz is incorporated. This important point allows us to make very specific predictions for the cosmological baryon number asymmetry and CP violation in neutrino oscillations. A measurement of the smallest neutrino mixing angle will sensitively test the FGY ansatz, in particular, in the case that three light neutrinos have a normal mass hierarchy.
