Abstract: Photoproduction is a useful tool in understanding the strong force in nature. To probe this, coherent vector meson photoproduction from the deuteron has been studied using CLAS at Jefferson Lab, Virginia, as a function of the photon energy and the 4-momentum transfer. Tagged photons with beam energies between 0.8 and 3.6 GeV were produced using the bremsstrahlung process incident on a deuterium target. Using the detection sample two vector meson channels (γd → ωd and γd → ρd) are investigated separately and their differential cross sections are measured. A rescattering model based on the Vector Meson Dominance is used to extract the total cross-section for the vector meson-Nucleon scattering. The results dramatically improve the world data in the kinematic regime investigated.
