论文摘要

我们介绍了Kamland中搜索MEV规模的电子抗神经活动的结果，这与Ligo/Pirgo协作在其第二和第三次观察过程中报道的60个引力波事件/候选者相吻合。我们发现在$ \ pm $ 500 s的计时窗口内没有明显的重合信号，并且目前为90％C.L.电子抗质体的上限在$ 10^{8} $ - $ 10^{13} \，{\ mathrm cm^2} $中，用于1.8-111 mev的能量范围内中微子能量。

We present the results of a search for MeV-scale electron antineutrino events in KamLAND in coincident with the 60 gravitational wave events/candidates reported by the LIGO/Virgo collaboration during their second and third observing runs. We find no significant coincident signals within a $\pm$ 500 s timing window from each gravitational wave and present 90% C.L. upper limits on the electron antineutrino fluence between $10^{8}$-$10^{13}\,{\mathrm cm^2}$ for neutrino energies in the energy range of 1.8-111 MeV.
