Rare Kaon Decays on the Lattice
Gino Isidori, Guido Martinelli, Paolo Turchetti
We show that long distance contributions to the rare decays K -> pi nu nu-bar and K -> pi l+ l- can be computed using lattice QCD. The proposed approach requires well established m…

SU(3)-breaking effects in kaon and hyperon semileptonic decays from lattice QCD
D. Becirevic, D. Guadagnoli, G. Isidori +7
We discuss the result of a recent quenched lattice calculation of the K -> pi vector form factor at zero-momentum transfer, relevant for the determination of |V_us| from K-> pi l n…
