Abstract

Nonleptonic weak decays are very sensitive to nonperturbative quark‐quark and quark‐antiquark correlations. It is shown that effects of scalar diquarks dominate strange particle decays and are responsible for the drastic ‖ΔI‖=1/2 enhancement observed in these transitions. They also give rise to a large long range contribution to the KL–KS mass difference. In more energetic processes, scalar diquarks are less important, but their contribution is still sizeable in inclusive D and Ds decays. The generation of virtual diquark pairs appears as an effective first step in the formation of baryons in B decays.
