Electroproduction of the omega meson was investigated in the p(e,e'p)omegareaction. The measurement was performed at a 4-momentum transfer Q2 ~ 0.5 GeV2.Angular distributions of the virtual photon-proton center-of-momentum crosssections have been extracted over the full angular range. These distributionsexhibit a strong enhancement over t-channel parity exchange processes in thebackward direction. According to a newly developed electroproduction model,this enhancement provides significant evidence of resonance formation in thegamma* p -> omega p reaction channel.Comment: 10 pages, 14 figures, typos and references correcte
