来自天体物理瞬变的高能中微子是标准模型之外的中微子物理学探测。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会在它们的光谱上留下印记，而且会在到达和延迟分布上留下印记。假设这种相互作用在中微子传播过程中最多只发生一次，我们给出了由BSM引起的中微子回波光曲线的一般解析公式。该公式可用于约束中微子-中微子散射、中微子- dm散射以及相对论粒子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.
