论文摘要
最近宣布的Katrin协作结果意味着有效的电子抗中性质量$ M_ {ν_{E}} $，$ M_ {ν_{E}} <0.8〜 {\ rm ev}/c ev}/c^{2} $。在这里，我们探讨了使用先前推断的中微子质量状态下的katrin上限结合的含义，$ m_ {i，{\ rm min}} \ gtrsim 0.4〜 {\ rm ev}/c ev}/c ev}/c^{2} $暗示着白矮人的稳定性和中性heater的稳定性所暗示的。通过将修订后的下限估计与Katrin的预期最终上限相结合，我们发现$ M_ {ν_{E}} $的可用参数空间可能会在未来几年内完全关闭。然后，当存在单个光无菌中微子风味以设定无菌中微子的质量限制时，我们会扩展参数。
Recently announced results from the KATRIN collaboration imply an upper bound on the effective electron anti-neutrino mass $m_{ν_{e}}$, $m_{ν_{e}}< 0.8~{\rm eV}/c^{2}$. Here we explore the implications of combining the KATRIN upper bound using a previously inferred lower bound on the smallest neutrino mass state, $m_{i,{\rm min}}\gtrsim 0.4~{\rm eV}/c^{2}$ implied by the stability of white dwarfs and neutron stars in the presence of long-range many-body neutrino-exchange forces. By combining a revised lower bound estimate with the expected final upper bound from KATRIN, we find that the available parameter space for $m_{ν_{e}}$ may be closed completely within the next few years. We then extend the argument when a single light sterile neutrino flavor is present to set a lower mass limit on sterile neutrinos.
