论文摘要
核心偏曲超新星的热MEV中微子发射提供了一个独特的机会，可以探测中微子领域的标准模型以外的物理。下微中微子实验（例如沙丘和Hyper-Kamiokande）可以分别检测$ \ Mathcal {O}（10^3）$和$ \ Mathcal {O}（10^4）$ netrinos在半乳酸超新星的情况下。当超新星中微子传播到地球时，它们可能通过隐藏的介体与局部暗物质相互作用，并且可能会延迟相对于初始中微子信号。我们表明，对于Sub-Mev暗物质，暗物质 - 中性相互作用的存在可能会导致中微子回声，并具有很大的时间延迟。在超新星的MEV中微子的光曲线中，此特征的不存在或存在使我们能够探测尚未通过暗物质直接检测实验探索的参数空间。
Thermal MeV neutrino emission from core-collapse supernovae offers a unique opportunity to probe physics beyond the Standard Model in the neutrino sector. The next generation of neutrino experiments, such as DUNE and Hyper-Kamiokande, can detect $\mathcal{O}(10^3)$ and $\mathcal{O}(10^4)$ neutrinos in the event of a Galactic supernova, respectively. As supernova neutrinos propagate to Earth, they may interact with the local dark matter via hidden mediators and may be delayed with respect to the initial neutrino signal. We show that for sub-MeV dark matter, the presence of dark matter-neutrino interactions may lead to neutrino echoes with significant time delays. The absence or presence of this feature in the light curve of MeV neutrinos from a supernova allows us to probe parameter space that has not been explored by dark matter direct detection experiments.
