First observation of electron antineutrinos from nuclear reactors at Super-Kamiokande

K. Abe, Y. Asaoka, M. Harada +244

In 2020, Super-Kamiokande entered the SK-Gd phase, improving its sensitivity to low-energy electron antineutrinos through the detection of neutrons captured on gadolinium dissolved…
