人们普遍认为，观察到低能轻子-CP破坏相并不会自动暗示在瘦子发生情景中重子不对称的存在。这一结论一般不成立，当味道的问题是相关的，并适当地考虑到瘦子的发生。我们用不同的例子说明了这一点，研究了中微子振荡中重子不对称性和破坏中微子的不对称性之间的关系，以及无中微子双β衰变中的有效Majorana质量。
It was commonly thought that the observation of low energy leptonic $CP$-violating phases would not automatically imply the existence of a baryon asymmetry in the leptogenesis scenario. This conclusion does not generically hold when the issue of flavor is relevant and properly taken into account in leptogenesis. We illustrate this point with various examples studying the correlation between the baryon asymmetry and the $CP$-violating asymmetry in neutrino oscillations and the effective Majorana mass in neutrinoless double beta decay.
