We investigate whether CP phases in the neutrino mixing matrix can be the source of the CP violation necessary to achieve leptogenesis. In general, low-energy CP violation in the neutrino sector is not directly linked to leptogenesis, but we show that the low-energy leptonic CP violation can give rise to the CP asymmetry required for leptogenesis in a minimal seesaw model where the Dirac neutrino mass matrix contains one-zero texture. Performing numerical analyses based on the current results of the global fit to neutrino data and the measurement of baryon asymmetry, we study how the CP phases in the neutrino mixing matrix can be constrained and show how lepton asymmetry is sensitive to two heavy Majorana neutrino masses as well as CP phases. From the constraints on the neutrino parameters, the values of the effective neutrino mass contributing to the amplitude of neutrinoless double beta decay are predicted.

我们调查中微子混合基质中的CP相是否可以成为实现瘦素形成所必需的CP违背的来源。通常，中微子领域的低能CP违反与瘦素生成没有直接关系，但是我们表明，在狄拉克中微子质量为最小的跷跷板模型中，低能瘦子CP违反会引起瘦素生成所需的CP不对称。矩阵包含一零纹理。基于当前对中微子数据的整体拟合和重子不对称性测量的当前结果进行数值分析，我们研究了中微子混合矩阵中的CP相如何受到约束，并显示出轻子不对称性如何对两个沉重的Majorana中微子质量敏感。以及CP阶段。根据中微子参数的约束，
