Kamiokande-II和IMB发现来自SN1987A的高能中微子的证据

Evidence of High-Energy Neutrinos from SN1987A by Kamiokande-II and IMB

Yuichi Oyama

摘要:

SN 1987 A的高能中微子是利用神冈Ⅱ实验和IMB实验记录的上行μ子进行搜寻的。在1987年8月11日至10月20日期间,从10度半径的角窗口,Kamiokande-II记录了两个上行μ子事件,IMB也记录了两个事件。这些上行的μ子被大气中微子的偶然巧合解释的概率计算为0.27%。这显示了来自SN 1987 A的高能中微子的可能证据。

英文摘要:

High-energy neutrinos from SN1987A were searched for using upward-going muons recorded by the Kamiokande-II experiment and the IMB experiment. Between 1987 August 11 and October 20, and from an angular window of 10 degree radius, two upward-going muon events were recorded by Kamiokande-II, and also two events were recorded by IMB. The probability that these upward-going muons were explained by a chance coincidence of atmospheric neutrinos was calculated to be 0.27%. This shows possible evidence of high-energy neutrinos from SN1987A.
