Abstract

We have studied pp annihilations at rest in liquid hydrogen into the final state ωηπ0 where ω decays to π0γ. This reaction is dominated by the production of α0(980) and contributions from a2(1320) and b10(1235). Upper limits for the production of an axial vector h1(1380) meson and vector mesons ω(1390), ω(1600), and φ(1680) decaying to ωη are given. The branching ratio of pp annihilation into ωηπ0 was determined to be (0.68±0.01±0.05)%.
