Title: Differential cross section for γdωd using CLAS at Jefferson Lab

Here, the cross section for coherent $$\omega$$-meson photoproduction off the deuteron has been measured for the first time as a function of the momentum transfer $$t = (P_{\gamma}-P_{\omega})^2$$ and photon energy $$E_{\gamma}$$ using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The cross sections are measured in the energy range $$1.4 < E_{\gamma} < 3.4$$ GeV. A model based on $$\omega-N$$ rescattering is consistent with the data at low and intermediate momentum transfer, $|t|$. For $$2.8 < E_{\gamma} < 3.4$$ GeV, the total cross-section of $$\omega-N$$ scattering is 30-40 mb in the framework of Vector Meson Dominance.
