Abstract

A new method, recently introduced for the lattice calculation of electromagnetic and isospin corrections to weak decays [1], is discussed. Using this method, for the first time, the electromagnetic effects in the leptonic decay rates pi(-) -> mu(-) (nu) over bar (mu) K- -> mu(-) (nu) over bar (mu) and have been evaluated in lattice QCD. Preliminary results for the electromagnetic corrections to charged (neutral) pion and kaon masses and leptonic decay rates are presented.
