Renormalizing a three-flavor lattice calculation of the two-photon contribution to $K_{L} \to I^¼^{+} I^¼^{-}$

En-Hung Chao, Norman Christ, Ceran Hu

The paper presents a method to determine charm‑mass dependent low‑energy constants needed for a three‑flavor lattice QCD calculation of the long‑distance two‑photon contribution to…

An exploratory calculation of $K_{L} \to I^¼^{+} I^¼^{-}$ decay from Lattice QCD at physical pion mass

Peter Boyle, En-Hung Chao, Norman Christ +3

We compute the complex, long-distance two-photon-exchange amplitude which contributes to the rare $K_{L} \to I^¼^{+} I^¼^{-}$ decay from lattice QCD. We use a $2 4^{3} \times 64$ ph…

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…

Two-photon contribution to the $K_{L} \to I^¼^{+} I^¼^{-}$ decay amplitude from a $1/ a \approx 1$ GeV lattice

En-Hung Chao, Ceran Hu

We present a lattice-QCD calculation of the long-distance two-photon contribution to the decay amplitude of a long-lived kaon to a pair of muons on a $2 4^{3} \times 64$ physical-pion-…
