The eV-scale sterile neutrino has been proposed to explain some anomalous results in experiments, \textit{such as} the deficit of reactor neutrino fluxes and the excess of $\bar{\nu}_\mu\to\bar{\nu}_e$ in LSND. This hypothesis can be tested by future core-collapse supernova neutrino detection independently since the active-sterile mixing scheme affects the flavor conversion of neutrinos inside the supernova. In this work, we compute the predicted supernova neutrino events in future detectors -- DUNE, Hyper-K, and JUNO -- for neutrinos emitted during the neutronization burst phase when the luminosity of $\nu_e$ dominates the other flavors. We find that for a supernova occurring within 10 kpc, the difference in the event numbers with and without sterile neutrinos allows to exclude the sterile neutrino hypothesis at more than $99\%$ confidence level robustly. The derived constraints on sterile neutrinos mixing parameters are comparably better than the results from cosmology and on-going or proposed reactor experiments by more than two orders of magnitude in the $\sin^22\theta_{14}$-$\Delta m_{41}^2$ plane.

用多个探测器通过核心坍缩超新星约束无菌中微子

已经提出 eV 尺度的无菌中微子来解释实验中的一些异常结果，\textit{例如}反应堆中微子通量的不足和 $\bar{\nu}_\mu\to\bar{\nu }_e$ 在 LSND 中。由于主动-无菌混合方案会影响超新星内部中微子的风味转换，因此该假设可以通过未来的核心坍缩超新星中微子检测独立进行验证。在这项工作中，我们计算了未来探测器（DUNE、Hyper-K 和 JUNO）中预测的超新星中微子事件，这些中微子在中子化爆发阶段发射的中微子，当 $\nu_e$ 的光度主导其他类型时。我们发现对于发生在 10 kpc 内的超新星，带有和不带有惰性中微子的事件数量的差异允许在超过 $99\%$ 置信水平上强有力地排除惰性中微子假设。在 $\sin^22\theta_{14}$-$\Delta m_{ 中，导出的对惰性中微子混合参数的约束比宇宙学和正在进行或提议的反应堆实验的结果好两个数量级以上41}^2$ 飞机。
