Abstract
We discuss a new estimate of in the kaon system. The present approach is based on the evaluation of the hadronic matrix elements of the \mbox{} effective quark lagrangian by means of the chiral quark model, with the inclusion of meson one-loop renormalization and NLO Wilson coefficients. The estimate here reviewed is fully consistent with the selection rule in decays, which is well reproduced within the same framework.
