Super-Kamiokande探测器可用于搜索与LIGO-Virgo合作（LVC）探测到的引力波时间重合的中微子。分析了低能（7-100 MeV）和高能（0.1-105 GeV）样品，以覆盖非常宽的中微子光谱。对GWTC-2目录中报告的39个引力波中的36个进行了后续检查;没有观察到明显超出背景的现象，与高能（低能）样本中的4.8（25.0）个预期事件相比，观察到10（24）个中微子。使用统计方法计算潜在符合性的显著性。对于每个观测，使用中微子方向和LVC天空图估计p值;最重要的事件（GW 190602_175927）与试验后p值7.8%（1.4σ）相关。此外，单独计算每个样品的通量限值，并将样品合并。由已识别的引力波源以中微子形式发射的能量受到限制，无论是对于给定的口味还是对于所有口味，假设不同口味之间均分，独立于每个触发器，并通过组合相同性质的源。
The Super-Kamiokande detector can be used to search for neutrinos in time coincidence with gravitational waves detected by the LIGO–Virgo Collaboration (LVC). Both low-energy (7–100 MeV) and high-energy (0.1–105 GeV) samples were analyzed in order to cover a very wide neutrino spectrum. Follow-ups of 36 (out of 39) gravitational waves reported in the GWTC-2 catalog were examined; no significant excess above the background was observed, with 10 (24) observed neutrinos compared with 4.8 (25.0) expected events in the high-energy (low-energy) samples. A statistical approach was used to compute the significance of potential coincidences. For each observation, p-values were estimated using neutrino direction and LVC sky map; the most significant event (GW190602_175927) is associated with a post-trial p-value of 7.8% (1.4σ). Additionally, flux limits were computed independently for each sample and by combining the samples. The energy emitted as neutrinos by the identified gravitational wave sources was constrained, both for given flavors and for all flavors assuming equipartition between the different flavors, independently for each trigger and by combining sources of the same nature.
