N ov 2 00 1 ηN Final State Interaction in incoherent Photoproduction of η - mesons from the Deuteron near Threshold

چکیده
An analysis of incoherent photoproduction of η mesons off the deuteron for photon energies from threshold to 800 MeV is presented. The dominant contribution , the γN-ηN amplitude, is described within an isobar model. Effects of the final state interactions in the N N as well as the ηN systems are included employing models derived within the meson-exchange approach. It is found that their consideration is important. Specifically, due to an interference effect the influence of the ηN final state interaction is enhanced in the reaction γd → npη close to threshold.

2 00 1 Incoherent Photoproduction of η - mesons from the Deuteron near Threshold
Incoherent photoproduction of the η-meson on the deuteron is studied for photon energies from threshold to 800 MeV. The dominant contribution, the γN-ηN amplitude, is described within an isobar model. The final state interaction derived from the CD-Bonn potential is included and found to be important for the description of the production cross section close to threshold. Possible effects from t...

Very recent data for the reaction γd→ηnp are analyzed within a model that includes contributions from the impulse approximation and next order corrections due to the np and ηN interactions in the final state. Comparison between the calculations and data indicate sizable contributions from the np and ηN final state interactions close to threshold.

The importance of three-body dynamics in the ηnp system in elastic and inelastic η-deuteron scattering as well as coherent and incoherent η photo-production on the deuteron in the energy region from threshold up to 30 MeV above has been investigated. It is shown that a restriction to first order rescat-tering with respect to the N N-and ηN-final state interactions, i.e., restriction to rescatte...
متن کاملFinal state interaction effects in η photoproduction on two - and three - body nuclei
The role of final state interaction in η photoproduction on a deuteron as well as on three-body nuclei is investigated within few-body scattering theory. Deviation of the theory from the available experimental results is briefly discussed. 1. Incoherent η photoproduction on a deuteron Photoproduction of η mesons on the deuteron near threshold is strongly influenced by final state interaction (F...
متن کاملInfluence of final state interaction on incoherent η - photoproduction on the deuteron near threshold ∗
Incoherent η-photoproduction on the deuteron is studied for photon energies from threshold up to 720 MeV. The elementary γN → ηN amplitude is constructed in the frame of a conventional isobar model. Effects of final state interaction are investigated and their role in the cross section as well as in polarization observables is found to be important. Inclusion of such effects leads to a satisfac...
