摘要：

One of the mysteries of the Okubo-Zweig-lizuka (OZI) rule is that it is characterized by a scale-LAMBDA-OZI that is small compared to a typical hadronic width-GAMMA, whereas unitarity would lead one to expect LAMBDA-OZI approximately-GAMMA. We show that while individual virtual decay channels contribute to OZI violation with this expected strength, the coherence between all such channels can conspire to make LAMBDA-OZI << GAMMA, as observed.
