论文摘要
我们研究了两种可ran义的超对称$ so（10）\ times a_4 $模块化模型的瘦素发生的预测，其中中微子质量主要由我所见类型的机理产生。 Lepton不对称的演变是根据三种重型主要中微子的三种味道密度矩阵方程来描述的，其中考虑了右手中微子的初始条件和热初始条件的消失。我们还基于Boltzmann方程提出了一个分析近似。我们发现参数空间的区域与测得的费米质量和混合参数以及宇宙的重子不对称区域兼容。讨论了对轻中微子质量的预测，中微子dobleβ衰变的有效质量和麻痹性CP违规阶段的预测。
We study the prediction for leptogenesis in two renormalizable supersymmetric $SO(10)\times A_4$ modular models in which the neutrino mass is dominantly generated by the type I seesaw mechanism. The evolution of the lepton asymmetries are described in terms of the three-flavored density matrix equations for three heavy Majorana neutrinos, where both vanishing initial condition and thermal initial condition of the right-handed neutrinos are considered. We also present an analytical approximation based on the Boltzmann equations. We find regions of parameter space compatible with the measured fermion masses and mixing parameters as well as the baryon asymmetry of the Universe. The predictions for the light neutrino masses, the effective mass in neutrinoless doble beta decay and the leptonic CP violation phases are discussed.
