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

En-Hung Chao, Norman Christ, Ceran Hu

The Standard Model prediction for the rare $K_{L} \to μ^{+} μ^{-}$ decay depends critically on the long-distance contribution coming from the exchange of two photons. Such a contribution ca…

An exploratory calculation of $K_{L} \to μ^{+} μ^{-}$ 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 $K_{L} \to μ^{+} μ^{-}$ decay from lattice QCD. We use a $2 4^{3} \times 64$ phys…

Two-photon contribution to the $K_{L} \to μ^{+} μ^{-}$ 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-…
