论文摘要
加多琳负载的超级kamiokande（SK-GD）和即将启动的Juno液体闪烁体检测器的出现标志着对弥漫性超新星中微子背景（DSNB）的全球灵敏度的实质性提高。本文回顾了在实验中与DSNB搜索最相关的检测属性，并估算了预期信号和背景水平。基于这些输入，我们分别和组合评估两个实验的灵敏度。使用简化的统计方法，我们发现SK-GD和JUNO都有可能在测量后10年内达到DSNB信号的$ 3 $σ$。合并后的结果可能会在未来十年内$5σ$发现DSNB信号。
The advent of gadolinium-loaded Super-Kamiokande (SK-Gd) and of the soon-to-start JUNO liquid scintillator detector marks a substantial improvement in the global sensitivity for the Diffuse Supernova Neutrino Background (DSNB). The present article reviews the detector properties most relevant for the DSNB searches in both experiments and estimates the expected signal and background levels. Based on these inputs, we evaluate the sensitivity of both experiments individually and combined. Using a simplified statistical approach, we find that both SK-Gd and JUNO have the potential to reach $>$3$σ$ evidence of the DSNB signal within 10 years of measurement. The combined results are likely to enable a $5σ$ discovery of the DSNB signal within the next decade.
