Study of Phi and f2'(1525) meson production in anti-p p annihilation at rest

Academic Article
Publication Date:
1998
abstract:
The reaction pbar p --> K+ K- pi0 was analysed for antiproton annihilations at rest at three hydrogen target densities. A strong dependence of the pbar p --> phi pi0 yield on the quantum numbers of the initial state is observed. The branching ratio of the phi pi0 channel from the 3S1 initial state is more than 15 times larger than the one from the 1P1 state. A large apparent violation of the OZI rule for tensor meson production from pp-annihilations from the P-waves (1++ + 2++) is observed, significantly exceeding the OZI-rule prediction.
