新的中微子自相互作用可以为无菌中微子暗物质（SνDM）的残余丰度开辟可行的参数空间。在这项工作中，我们使用核心坍缩超新星来约束遗迹目标，该超新星具有与早期宇宙时代相同的基本过程和类似的环境，当时SνDM占主导地位。我们详细计算了大质量标量介导的中微子自相互作用对超新星冷却速率的影响，包括在等离子体物质存在非零化学势的情况下推导热势。我们的结果表明，超新星冷却的论点可以覆盖中微子自相互作用参数空间，补充了地球和宇宙学探测。
Novel neutrino self-interaction can open up viable parameter space for the relic abundance of sterile-neutrino dark matter (SνDM). In this work, we constrain the relic target using core-collapse supernova which features the same fundamental process and a similar environment to the early universe era when SνDM is dominantly produced. We present a detailed calculation of the effects of a massive scalar mediated neutrino self-interaction on the supernova cooling rate, including the derivation of the thermal potential in the presence of non-zero chemical potentials from plasma species. Our results demonstrate that the supernova cooling argument can cover the neutrino self-interaction parameter space that complements terrestrial and cosmological probes.
