Description
The major decay rates of the charged pion and kaon mesons are to the end state of a muon and neutrino. This mode contributes over 99.9 percent to the pion decay, and about 64 percent to the kaon decay.
Analysing this decay on the lattice could lead to improved values for the meson decay constants and the parameters in the CKM matrix. High accuracy predictions will need to have QED effects included. We present some initial simulations taking account of the QED corrections by including a partially quenched muon propagator with its photon cloud.
