论文摘要
我们研究了$（10）$启发的瘦化生成之间的绝对中微子质量与中微子混合参数之间的联系。我们表明，未知中微子混合参数的当前有利值指向绝对中微子质量量表的值，该值将通过宇宙学观察结果和中微子双β衰减实验进行充分测试。 In particular, for $m_{D2}/m_{\rm charm} \leq 5$, where $m_{D2}$ is the intermediate Dirac neutrino mass, and for current best fit values of the Dirac phase $δ$ and the atmospheric neutrino mixing angle $θ_{23}$, we derive a lower bound on the neutrinoless double beta decay effective neutrino mass $ m_ {ee} \ gtrsim 31 \，{\ rm mev} $以及中微子质量的总和$ \ sum_i m_i \ gtrsim 125 \，{\ rm mev} $。这些下微中微子质量的这些低界限目前受到全局分析的青睐，在[155^\ circ，240^\ circ] $和$θ_{23} $中大约$δ\在第二个八分之一中。如果该区域的值将通过未来计划的长基线实验确认，那么尽管中微子质量正常被订购，但下一代中微子双β衰变实验的信号仍会预期。在该区域之外，下限强烈放松，但允许值范围的很大一部分仍然可以测量最轻的中微子质量。因此，在接下来的几年中，低能中微子实验将提供非常严格的$（10）$启发的瘦素发生的测试，从而受到严重的限制或有力的证据。
We study the connection between absolute neutrino mass and neutrino mixing parameters within $SO(10)$-inspired leptogenesis. We show that current favoured values of the unknown neutrino mixing parameters point toward values of the absolute neutrino mass scale that will be fully tested by cosmological observations and neutrinoless double beta decay experiments during next years. In particular, for $m_{D2}/m_{\rm charm} \leq 5$, where $m_{D2}$ is the intermediate Dirac neutrino mass, and for current best fit values of the Dirac phase $δ$ and the atmospheric neutrino mixing angle $θ_{23}$, we derive a lower bound on the neutrinoless double beta decay effective neutrino mass $m_{ee} \gtrsim 31\,{\rm meV}$ and on the sum of the neutrino masses $\sum_i m_i \gtrsim 125\,{\rm meV}$. These lower bounds hold for normally ordered neutrino masses, as currently favoured by global analyses and approximately for $δ\in [155^\circ,240^\circ]$ and $θ_{23}$ in the second octant. If values in this region will be confirmed by future planned long baseline experiments, then a signal at next generation neutrinoless double beta decay experiments is expected, despite neutrino masses being normally ordered. Outside the region, the lower bounds strongly relax but a great fraction of the allowed range of values still allows a measurement of the lightest neutrino mass. Therefore, in the the next years low energy neutrino experiments will provide a very stringent test of $SO(10)$-inspired leptogenesis, resulting either in severe constraints or in a strong evidence.
