Abstract
Chiral perturbation theory relates the matrix element to the matrix element . The latter matrix element is measured in decay and the former matrix element is relevant for the predictions that the standard model makes for nonconservation in mixing. In this paper the corrections of order to lowest-order chiral perturbation theory (i.e., order ) for these matrix elements are computed. The correction is large for the matrix element indicating a breakdown of chiral perturbation theory.
