Prospects for a lattice computation of rare kaon decay amplitudes: $K\to \pi {\ell }^{+}{\ell }^{-}$ decays

N. H. Christ, X. Feng, A. Portelli +1

The rare kaon decays $K\to \pi {\ell }^{+}{\ell }^{-}$ and $K\to \pi \nu \bar{\nu }$ are flavor changing neutral current (FCNC) processes and hence promising channels with which to probe the limits of the s…
