Experimental Study of Rare Kaon Decays at J-PARC with KOTO and KOTO II
J. K. Ahn, E. Augustine, L. Bandiera +62
The rare kaon decay is extremely sensitive to new physics, because the contribution to this decay in the Standard Model (SM) is highly suppressed and known very a…

Limits on the Low-Energy Electron Antineutrino Flux from the Brightest GRB of All Time
T. Araki, S. Chauhan, K. Chiba +69
The electron antinuetrino flux limits are presented for the brightest gamma-ray burst (GRB) of all time, GRB221009A, over a range of 1.8-200 MeV using the Kamioka Liquid Scintillat…
