Do we understand the ηN interaction from the near-threshold η photoproduction on the deuteron?

摘要

The effects of final-state interaction in incoherent η photoproduction on a deuteron are studied within a three-body approach including a realistic NN potential. The results are compared with available data, and differences with other theoretical predictions are analyzed. The role of the interaction and the possibility of extracting the ηN scattering parameters from this reaction are discussed.
