    "abstract": "We analyze the double polarization asymmetry of the omega-meson\nphotoproduction in the vector-meson-dominance model of diffractive production\nand the one-pion exchange model. We find that the longitudinal beam-target\nasymmetry is very sensitive to the real part of the diffractive photoproduction\namplitude and to the sign of the omega-pi-gamma coupling because of the\ndifferent spin structures of the amplitudes associated with the different\nmechanisms.",
