OZI Rule Violation in p pbar Annihilation into phi pi pi by Two Step Processes
arXiv:hep-ph/9707491 · doi:10.1007/s100500050036
Abstract
The phi pi+ pi- production in p pbar annihilation at rest is strongly enhanced by a two step mechanism with intermediate K Kbar pi pi states. The relative yield of the phi production due to the resonant final state interaction decreases with increasing total energy of the p pbar system.
