Exploratory lattice QCD study of the rare kaon decay $K^{+}\to {\pi }^{+}\nu \bar{\nu }$

Ziyuan Bai, Norman H. Christ, Xu Feng +3

In Ref [1] we have presented the results of an exploratory lattice QCD computation of the long-distance contribution to the $K^{+}\to {\pi }^{+}\nu \bar{\nu }$ decay amplitude. In the present paper…
