\(η\) photoproduction off the deuteron and low-energy \(η\)-nucleon interaction

By S. Nakamura and others
We study \(\eta\) photoproduction off the deuteron (\(\gamma d\to\eta pn\)) at a special kinematics: \(\sim 0.94\) GeV of the photon beam energy and \(\sim 0^\circ\) of the scattering angle of the proton. This kinematics is ideal to extract the low-energy \(\eta\)-nucleon scattering parameters such as \(a_{\eta N}\) (scattering length) and... Show more
