Abstract
We study the transition from perturbative QCD to Chiral Dynamics (linear {sigma} model), which describe physics between M{sub W} and {mu}, and between {mu} and M{sub {pi}}, respectively. This is done within the context of K decays. The smoothness of the transition is shown by comparing the explicit form of the anomalous dimension matrices in both pictures and by checking the approximate cancellation of the {mu} dependence. 6 refs., 2 figs.
