Connection between nonleptonic Ksub(2π) and Dsub(Kπ) decays and constraints on the quark-spectator model
Description
A unified picture of the curent-current amplitudes for Ksub(2π) and Dsub(Kπ) weak nonleptonic decays requires the spectator-quark model to be valid. These amplitudes are consistent with data and QCD color suppression provided the color-suppressed to color-enhanced amplitude ratio is of opposite sign as compared to that found by neglecting color-octet terms in the Fierz identity
