论文摘要
来自天体物理瞬变的高能中微子是标准模型以外的中微子物理学的探针。特别是，中微子与宇宙中微子背景或暗物质（DM）的非标准相互作用不仅在其光谱上，而且还具有到达和时间延迟的分布上。假设相互作用最多发生在中微子传播期间一次，我们为BSM诱导的中微子回声的光曲线提供了一般的分析公式。该公式可用于约束中微子 - 中微子散射，中微子-DM散射以及相对论颗粒所经历的其他散射过程。
High-energy neutrinos from astrophysical transients serve as a probe of neutrino physics beyond the Standard Model. In particular, nonstandard interaction of neutrinos with the cosmic neutrino background or dark matter (DM) may have imprints on not only their spectra but also the arrival and time-delay distributions. Assuming that the interaction occurs at most once during the neutrino propagation, we provide general analytic formulas for light curves of the neutrino echoes induced by BSM. The formulas can be used for constraining neutrino-neutrino scattering, neutrino-DM scattering, and other scattering processes experienced by relativistic particles.
