标题： Evaluation of expected solar flare neutrino events in the IceCube observatory

摘要： 自上世纪八十年代末以来，并且响应 Homestake 实验中与太阳耀斑同时发生的总中微子通量增加的报道，太阳中微子探测器一直在寻找太阳耀斑信号。 由加速质子与太阳大气碰撞产生的介子衰变产生的中微子，将为加速过程的基本物理提供一个全新的窗口。 在我们的研究中，我们重点关注位于地理南极的 IceCube 中微子天文台，这是一个立方千米规模的中微子探测器。 由于其超新星数据采集系统及其专注于低能中微子的 DeepCore 组件，IceCube 可能对太阳耀斑中微子敏感，从而允许测量信号或建立更严格的太阳耀斑中微子通量上限。 我们提出了一种基于堆叠方法的时间分布分析方法，并使用 Geant4 工具包评估了 IceCube 中可能存在的太阳耀斑信号。 显示英文摘要

摘要： Since the end of the eighties and in response to a reported increase in the total neutrino flux in the Homestake experiment in coincidence with a solar flare, solar neutrino detectors have searched for solar flare signals. Neutrinos from the decay of mesons, which are themselves produced in collisions of accelerated protons with the solar atmosphere, would provide a novel window on the underlying physics of the acceleration process. For our studies we focus on the IceCube Neutrino Observatory, a cubic kilometer neutrino detector located at the geographical South Pole. Due to its Supernova data acquisition system and its DeepCore component, dedicated to low energy neutrinos, IceCube may be sensitive to solar flare neutrinos and thus permit either a measurement of the signal or the establishment of more stringent upper limits on the solar flare neutrino flux. We present an approach for a time profile analysis based on a stacking method and an evaluation of a possible solar flare signal in IceCube using the Geant4 toolkit.
