AI中文摘要：
核心坍缩超新星是检验标准模型之外物理（BSM）的强大实验室，特别是对于与标准模型粒子微弱相互作用的新轻态。在这项工作中，我们首次研究了核心坍缩超新星内部通过中微子-中微子散射过程产生暗物质（DM）的机制，该过程有助于过度的冷却。通过结合最先进的超新星模拟数据，我们推导出对具有有效中微子耦合的亚GeV暗物质的严格且稳健的限制。我们发现现有的和预期的间接探测约束相当弱。我们的超新星冷却界限对DM-中微子参考截面的改进可以将间接探测极限提高超过十个数量级，对于质量低于$\mathcal{O}(100)$ MeV的暗物质，并且它还可以与其他宇宙学约束提供强互补性。我们的结果突显了核心坍缩超新星对微弱相互作用粒子的非凡敏感性，并激励未来的超新星中微子观测作为探测轻暗扇区的有力工具。
英文摘要：
Core-collapse supernova serve as a powerful laboratory for testing physics beyond the Standard Model (BSM), particularly regarding new, light states interacting feebly with SM particles. In this work, we investigate for the first time the production of dark matter (DM) via the neutrino-neutrino scattering processes inside a core-collapse supernova, which contributes to the excessive cooling. By incorporating state-of-the-art supernova simulation data , we derive stringent and robust limits on sub-GeV dark matter with effective couplings to neutrinos. We find that the existing and projected constraints from indirect detection are quite weak. Our supernova cooling bounds on DM-neutrino reference cross section can improve indirect detection limits more than ten orders of magnitude for DM masses below $\mathcal{O}(100)$ MeV, and it can also provide strong complementarity with other cosmological constraints. Our results highlight the exceptional sensitivity of core-collapse supernova to feebly interacting particles and motivate future supernova neutrino observations as a powerful probe of light dark sectors.
