Direct vs. final state tensor meson photoproduction - amplitude analysis

Tensor meson photoproduction is described as either a direct production process or a consequence of the final state [pi][pi] interactions. We calculate the mass distributions for selected partial waves and confront our predictions with the measurements of the CLAS experiment. We also point out the structures in the photoproduction amplitudes which may result in observable effects able to indicate the dominant tensor meson photoproduction mechanism.
