论文摘要
我们在$ su（5）\ times \ Mathcal {t} _ {13} $“非对称纹理”的背景下研究了非共鸣的热卵裂生成，其中Dirac和Majoraana $ {CP} $均来自Tramimaimal Seesaw Mixing Matrix的单个相。我们表明，只有在考虑右手中微子质量的$ \ Mathcal {o}（10^9-9-10^{12}）$ $ $ $ $ $ $ $ $ $ $ $ \ text {gev} $时，才能在此模型中解释宇宙的重子不对称。 Baryon不对称的符号还确定了先前预测的Dirac $ \ require {Cancel} \ CANCAL {CP} $ phase $ |δ__{CP} | =1.32π$，与最新的全局拟合$δ_{cp}^{pdg} = 1.37 \ pm0.17π$一致。
We investigate non-resonant thermal leptogenesis in the context of the $SU(5) \times \mathcal{T}_{13}$ "asymmetric texture", where both Dirac and Majorana ${CP}$ violation arise from a single phase in the tribimaximal seesaw mixing matrix. We show that the baryon asymmetry of the universe can be explained in this model only when flavor effects are considered for right-handed neutrino masses of $\mathcal{O}(10^9 - 10^{12})$ $\text{GeV}$. The sign of the baryon asymmetry also determines the sign of the previously predicted Dirac $\require{cancel}\cancel{CP}$ phase $|δ_{CP}| = 1.32π$, consistent with the latest global fit $δ_{CP}^{PDG} = 1.37 \pm 0.17π$.
