论文摘要
新颖的中微子自我互动可以为无菌 - 中性黑物质（s $ν$ dm）开放可行的参数空间。在这项工作中，我们使用核心崩溃的超新星限制了遗物目标，该核心崩溃的超新星具有相同的基本过程和与早期宇宙时代相似的环境，而S $ν$ dm主要生产出来。我们介绍了大规模标量介导的中微子自我相互作用对超新星冷却速率的影响的详细计算，包括在存在于血浆物种的非零化学电位的情况下衍生热势。我们的结果表明，超新星冷却论点可以涵盖与陆生和宇宙学探针相辅相成的中微子自我交互参数空间。
Novel neutrino self-interaction can open up viable parameter space for the relic abundance of sterile-neutrino dark matter (S$ν$DM). 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 S$ν$DM 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.
