Photoproduction of theωmeson on the proton near threshold

An experimental study of ω photoproduction on the proton was conducted by using the Crystal Ball and TAPS multiphoton spectrometers together with the photon tagging facility at the Mainz Microtron MAMI. The γp→ωp differential cross sections are measured from threshold to the incident-photon energy E_γ=1.40 GeV $(W=1.87$ GeV for the center-of-mass energy) with 15-MeV binning in E_γ and full production-angle coverage. The quality of the present data near threshold gives access to a variety of interesting physics aspects. As an example, an estimation of the ωN scattering length α_ωp is provided.
