Abstract :
We present the first lattice calculation of the matrix element of the electromagnetic operator 〈π0|Qγ+|K0〉, where Qγ+=(Qde/16π2)(s̄LσμνFμνdR+s̄RσμνFμνdL). This matrix element plays an important rôle, since it contributes to enhance the CP violating part of the KL→π0e+e− amplitude in supersymmetric extensions of the Standard Model.
