Abstract
The resonance model is used to analyze the omega- and phi-meson angular distributions in proton-proton collisions at sqrt{s} = 2.83 and 2.98 GeV. The assumption of dominant contributions from N^*(1720)3/2+ and N^*(1900)3/2+ resonances which both have, according to the pi N scattering multichannel partial-wave analysis and/or quark models predictions, dominant p_{1/2} N-omega decay modes yields the right pattern of the omega angular distribution at sqrt{s} = 2.83 GeV. The angular distribution at sqrt{s} = 2.98 GeV can be reproduced assuming the dominance of N^*(2000)5/2+ and N^*(1900)3/2+. The experimental phi-meson angular distributions do not shown any asymmetry which requires the existence of a massive negative-parity spin-half resonance. This resonance could be identified with the N^*(2090)1/2-.
