The cross section for coherent ω-meson photoproduction off the
deuteron has been measured for the first time as a function of the momentum
transfer t=(Pγ−Pω)2 and photon energy Eγ using
the CLAS detector at the Thomas Jefferson National Accelerator Facility. The
cross sections are measured in the energy range 1.4<Eγ<3.4 GeV. A
model based on ω−N rescattering is consistent with the data at low and
intermediate momentum transfer, ∣t∣. For 2.8<Eγ<3.4 GeV, the
total cross-section of ω−N scattering, based on fits within the
framework of the Vector Meson Dominance model, is in the range of 30-40 mb.Comment: 8 pages, 5 figure
