Abstract:
The photoproduction of omega mesons off protons has been studied at the Bonn ELSA accelerator from threshold to E-gamma = 1700 MeV. Linearly polarized beams were produced via coherent bremsstrahlung. Large photon asymmetries in excess of 50% were obtained. For the first time the pion asymmetries associated with the omega -> pi(0)gamma decay were measured and found close to zero. The asymmetries indicate s-channel resonance formation on top of t-channel exchange processes.
