Abstract: | We study ¯pp annihilation at rest intoπφ andγφ. Rescattering by ¯K*K+K*¯K and ρ+ρ? for ¯pp→πφ states is sizable, of order (0.90 to 2.6) × 10?4 in the branching ratio, but smaller than experiment. For ¯pp→γφ the rescattering contributions are negligible, but theγφ channel is well explained by aρφ intermediate state combined with vector meson dominance. |
