论文摘要
我们提出了一项关于辐射Seesaw模型中谐振诱导生成的研究。我们考虑了两种准脱位右撇子中微子实现共振的诱变发生的情况，并且通过中微子混合矩阵中存在的CP阶段发生瘦肉发生所需的CP违反。通过从当前全局数据中获取最佳拟合值的三个中微子混合角度和两个质量方差异来进行数值分析。我们已经展示了Baryon不对称的预测值如何取决于Dirac和Majoraana CP阶段。有了质量参数的特殊选择，该模型更喜欢基于预测的Baryon不对称值的中微子质量的正常层次结构。使用受约束的CP阶段，我们评估了与中微子双β衰减有关的有效中微子质量。
We present a study of resonant leptogenesis in a radiative seesaw model. We consider the case where two quasi-degenerate right-handed neutrinos realize resonant leptogenesis, and the CP violation necessary to achieve leptogenesis occurs through the CP phases present in the neutrino mixing matrix. A numerical analysis is performed by taking the best-fit values from the current global data for three neutrino mixing angles and two mass-squared differences. We have shown how the predicted value of baryon asymmetry depends on the Dirac and Majorana CP phases. With the particular choice for the mass parameters, this model prefers a normal hierarchy of neutrino masses based on the value of baryon asymmetry predicted. Using the constrained CP phases, we evaluate the effective neutrino mass, which is relevant to the neutrinoless double beta decay.
