| Summary: | <jats:title>Abstract</jats:title> <jats:p>We present the results of a search for MeV-scale electron antineutrino events in KamLAND 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 ±500 s timing window from each gravitational wave and present 90% C.L. upper limits on the electron antineutrino fluence between 10<jats:sup>8</jats:sup> and 10<jats:sup>13</jats:sup> cm<jats:sup>−2</jats:sup> for neutrino energies in the energy range of 1.8-111 MeV.</jats:p> |
