AI 中文摘要
我们展示了如何将假设序贯主导（Sequential Dominance）的唯象模型构建扩展到右旋中微子质量简并的情况。由于该框架可容纳共振轻子生成，我们将其命名为共振序贯主导（Resonant Sequential Dominance）。随后，我们利用本工作提出的新型中微子混合矩阵假设 TBC3，在共振序贯主导框架内研究与当前中微子数据兼容的狄拉克质量矩阵纹理。此外，我们提出一个具有 $A_4 \times (Z_3)^4 \times (Z_2)^2$ 对称性的拉格朗日量，该量与中微子振荡数据一致且能成功驱动共振轻子生成。最后，我们发现，要解释观测到的宇宙重子不对称性，最轻右旋中微子质量需满足 $0.13\text{ TeV} \le m_{N_1} \le 230\text{ TeV}$。
英文摘要
We demonstrate how phenomenological model construction assuming Sequential Dominance can be extended to cases with degenerate right-handed neutrino masses. Because this framework accommodates resonant leptogenesis, we designate it as Resonant Sequential Dominance. We then investigate Dirac mass matrix textures compatible with current neutrino data within Resonant Sequential Dominance, utilizing a novel neutrino mixing matrix ansatz termed TBC3, proposed in this work. Additionally, we present an $A_4 \times (Z_3)^4 \times (Z_2)^2$-symmetric Lagrangian that is consistent with neutrino oscillation data and successfully drives resonant leptogenesis. Lastly, we find that accounting for the observed baryon asymmetry of the Universe requires the lightest right-handed neutrino mass to lie in the range $0.13\text{ TeV} \le m_{N_1} \le 230\text{ TeV}$.
