Complete lattice QCD calculation of form factors
R. Di Palma, R. Frezzotti, G. Gagliardi +6
We present the first complete lattice QCD calculation of the four structure-dependent form factors governing the rare charged kaon decay $K^- \to \ell^- \barν_\ell \ell'^+ \ell'^-…

Rare kaon decays : Standard Model predictions from lattice QCD
R. Di Palma, R. Frezzotti, G. Gagliardi +6
Weak decays of charged kaons with an additional lepton-antilepton pair, (), are suppressed at order $O(G_{F}^{2}α_…
