论文摘要

SNO+协作报告了Cherenkov探测器中反应堆抗神经毒素的第一个证据。最近的核反应堆位于加拿大安大略省240 km。该分析使用的事件的能量低于任何先前的分析,并具有大型水Cherenkov检测器。两种分析方法用于在190天的数据中区分反应堆抗神经素和背景事件,并产生一致的抗神经毒素的证据,其综合意义为3.5 $σ$。

The SNO+ Collaboration reports the first evidence of reactor antineutrinos in a Cherenkov detector. The nearest nuclear reactors are located 240~km away in Ontario, Canada. This analysis uses events with energies lower than in any previous analysis with a large water Cherenkov detector. Two analytical methods are used to distinguish reactor antineutrinos from background events in 190 days of data and yield consistent evidence for antineutrinos with a combined significance of 3.5$σ$.
