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 ver…

Measurement of muon flux behind the beam dump of the J-PARC Hadron Experimental Facility
T. Matsumura, Y. Hirayama, G. Y. Lim +4
A muon-flux measurement behind the beam dump of the J-PARC Hadron Experimental Facility was performed with a compact muon detector that can be inserted into a vertical observing ho…
