Abstract
The OZI suppressed reactions¯pp→φφ and¯pp→πφ are reanalyzed, evaluating the unitarity contributions from two meson intermediate states with full spin, partially correcting earlier results. An estimate for¯pp→ππφ without spin is also given. Together with earlier VDM results for¯pp→φγ the conservative estimates reported here easily explain the observed rates for all theφ meson channels considered.
