$K\toÏγ^*γ^*$ transitions at leading order and beyond
Tomáš Husek
The transition amplitude of a kaon to a pion and two off-shell photons is studied. First, it is computed at leading order (one-loop level) of the Chiral Perturbation Theory expansi…
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…
Kaon Physics: A Cornerstone for Future Discoveries
Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153
The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…
Proposal of the KOTO II experiment
Jung Keun Ahn, Antonella Antonelli, Giuseppina Anzivino +79
The KOTO II experiment is proposed to measure the branching ratio of the decay at J-PARC. With a beamline to extract long-lived neutral kaons at 5 degrees from…
