    Description
    The present theoretical accuracy on some phenomenologically relevant light meson's observables (such as Kaon's decay constants, etc.) cannot be improved without taking into account the difference between the up and down quark masses. In order to calculate on the lattice the so-called "QCD isospin breaking effects" one needs to address both theoretical and numerical problems. In this talk I discuss a general method to calculate these effects and show preliminary results for FK and for the decay rates of Kl3 semileptonic decays.
