Long-distance contributions in $K\to \pi l^{+}{l}^{-}$ Decays

Abstract

This talk gives a short summary of some work \cite{FGEdeR04} realized in collaboration with E. de Rafael and concerning $K\raπ\ell^+ \ell^-$ decays, in a combined framework of Chiral Perturbation Theory and Large--$N\_c$ QCD under the dominance of a minimal narrow resonance structure.
