摘要：

We have studied ppBAR annihilations at rest in liquid hydrogen into the final state omegaetapi0 where omega decays to pi0gamma. This reaction is dominated by the production of a0(980) and contributions from a2(1320) and b1(0) (1235). Upper limits for the production of an axial vector h1'(1380) meson and vector mesons omega(1390), omega(1600), and phi(1680) decaying to omegaeta are given. The branching ratio of ppBAR annihilation into omegaetapi0 was determined to be (0.68 +/- 0.01 +/- 0.05)%.
