Abstract:
Electroproduction of the ω meson was investigated in 1H(e,e′p)ω reaction. The measurement was performed at a four-momentum transfer Q 2≈0.5 GeV 2. Angular distributions of the virtual photon-proton center-of-momentum cross sections have been extracted over the full angular range. These distributions exhibit a strong enhancement over t-channel parity exchange processes in the backward direction. According to a newly developed electroproduction model, this enhancement provides significant evidence of resonance formation in the γ*p → ωp reaction channel.
