论文摘要
即将进行的Hyper-Kamiokande（HyperK）实验有望检测到弥漫性超新星中微子背景（DSNB）。这需要思考所有可能的背景来源。将歼灭中微子歼灭的Sub-GEV暗物质（DM）是迄今尚未考虑的潜在背景。我们模拟DSNB和DM信号，以及HyperK检测器中的背景。我们发现，DM诱导的中微子确实可以改变DSNB物理学参数的正确值的提取。由于DSNB是各向同性信号，并且DM主要来自银河系中心，因此我们表明可以通过On-Off分析来缓解这种效果。
The upcoming Hyper-Kamiokande (HyperK) experiment is expected to detect the Diffuse Supernova Neutrino Background (DSNB). This requires to ponder all possible sources of background. Sub-GeV dark matter (DM) which annihilates into neutrinos is a potential background that has not been considered so far. We simulate DSNB and DM signals, as well as backgrounds in the HyperK detector. We find that DM-induced neutrinos could indeed alter the extraction of the correct values of the parameters of interest for DSNB physics. Since the DSNB is an isotropic signal, and DM originates primarily from the Galactic centre, we show that this effect could be alleviated with an on-off analysis.
