Neutrino telescopes, including IceCube, can detect galactic supernova events by observing the collective rise in photomultiplier count rates with a subsecond time resolution. Leveraging precise timing, we demonstrate for the first time the ability of neutrino telescopes to explore new weakly coupled states emitted from supernovae and subsequently decaying to neutrinos. Our approach utilizes publicly available packages, asteria and snewpy, for simulating detector responses and parametrizing neutrino fluxes originating from the standard model and new physics. We present results for two beyond-the-standard model scenarios and introduce the tool developed for testing a diverse range of new physics models.
包括冰立方在内的中微子望远镜，能够通过以亚秒级的时间分辨率观测光电倍增管计数率的集体上升来探测银河系中的超新星事件。利用精确的计时，我们首次证明了中微子望远镜有能力探索超新星发射出的新的弱耦合态，并随后衰变为中微子。我们的方法利用公开可用的软件包asteria和snewpy，来模拟探测器响应并对源自标准模型和新物理的中微子通量进行参数化。我们展示了两个超出标准模型情景的结果，并介绍了为测试各种新物理模型而开发的工具。
