我们报告了在超级神冈（SK）中微子搜索的结果，与第一个检测到的引力波（GW）产生的二元中子星合并，GW 170817，其次是短的伽马射线爆发，GRB 170817 A，和kilonova/macronova的重合信号。我们在引力波探测时间周围±500 s的时间窗口内以及探测后的14天内搜索了3.5 MeV至1000 PeV范围内的符合中微子事件。在这两个时间窗内都没有观察到明显的中微子信号。我们计算了GW 170817中微子注量的90%置信水平上限。从1.6 GeV以上能区的上行μ子事件来看，μ子中微子（μ子反中微子）的中微子注量极限为16.0 − 0.6 + 0.7（21.3 − 0.8 + 1.1）cm−2，在NGC 4993天顶角附近的误差范围为±5°，能谱假设指数为−2。中微子能量小于100兆电子伏，其发射机制将是不同的比更高能量的中微子的注量极限，也计算。假设反电子中微子的费米-狄拉克能谱的平均能量为20 MeV，则反电子中微子的平均能量为6.6 × 107 cm−2。
We report the results of a neutrino search in Super-Kamiokande (SK) for coincident signals with the first detected gravitational wave (GW) produced by a binary neutron-star merger, GW170817, which was followed by a short gamma-ray burst, GRB170817A, and a kilonova/macronova. We searched for coincident neutrino events in the range from 3.5 MeV to ∼100 PeV, in a time window ±500 s around the gravitational wave detection time, as well as during a 14-day period after the detection. No significant neutrino signal was observed for either time window. We calculated 90% confidence level upper limits on the neutrino fluence for GW170817. From the upward-going-muon events in the energy region above 1.6 GeV, the neutrino fluence limit is 16.0 − 0.6 + 0.7 ( 21.3 − 0.8 + 1.1 ) cm−2 for muon neutrinos (muon antineutrinos), with an error range of ±5° around the zenith angle of NGC4993, and the energy spectrum is under the assumption of an index of −2. The fluence limit for neutrino energies less than 100 MeV, for which the emission mechanism would be different than for higher-energy neutrinos, is also calculated. It is 6.6 × 107 cm−2 for anti-electron neutrinos under the assumption of a Fermi–Dirac spectrum with average energy of 20 MeV.
