Rates for the reactions antiproton-proton --> pi phi and gamma phi

M. P. Locher, Y. Lu, B. S. Zou

We study antiproton-proton annihilation at rest into $\pi \varphi$ and $\gamma \varphi$. Rescattering by $\overline{K^{\ast }}K+K^{\ast }\overline{K}$ and ${\rho }^{+}{\rho }^{-}$ for $\overline{p}p\to \pi \varphi$ states is si…
