Coherent eta photoproduction on the deuteron in the S 11 resonance region
نویسندگان
چکیده
Coherent eta photoproduction on the deuteron is studied in the S 11 resonance region neglecting eta rescattering and two-body processes. For the elementary reaction on the nucleon, we have considered the dominant S 11 (1535) resonance and as background the nucleon pole terms as well as and ! meson exchange. We have studied the innuence of diierent choices for the neutron resonance amplitude, diierent prescriptions for xing the invariant mass of the resonance amplitude and diierent methods for deriving the elementary production amplitude for an arbitrary reference frame.

Coherent π 0 and η Photoproduction on the Deuteron
Coherent pion photoproduction, d(γ, π 0)d, is calculated in a coupled channels approach in momentum space using an elementary production operator that includes Born terms, vector meson exchange and M 1/E2 ∆-resonance exci-tation. The final state interaction is treated in the KMT multiple scattering approach that describes πd elastic scattering well. Differential cross sections are found to agre...
متن کاملRescattering effects in coherent pion photoproduction on the deuteron in the ∆ resonance region ∗
Within a dynamical model, rescattering effects are studied in coherent pion photoproduction on the deuteron in the ∆(1232) resonance region. The model consists of a system of coupled equations for the N∆, NNπ and NN channels. Pion rescattering leads in general to a significant reduction of total and differential cross sections resulting in a better description of experimental data. Only a few p...
متن کاملPhotoproduction of Eta and Etaprime Mesons on the Nucleon
The isobar models η-MAID and η-MAID have been used to analyze new data on quasifree η photoproduction on the deuteron from Bonn and recent η data on the proton from Jlab. In η photoproduction on the neutron a bump around W = 1700 MeV was observed which could possibly arise from a narrow P11 state that is discussed as a nonstrange member of the Θ antidecuplett. In η photoproduction on the proton...

Incoherent photoproduction of pions on the deuteron in the first resonance region is investigated with special emphasis on single-spin asymmetries. For the elementary pion production operator an effective Lagrangian model which includes the standard pseudovector Born terms and a resonance contribution from the ∆(1232)-excitation is used. Single-spin asymmetries, both for charged and neutral pio...
متن کاملQuasifree Pion Photoproduction on the Deuteron in the ∆ Region 1
Photo production of pions on the deuteron is studied in the spectator nucleon model. The Born terms of the elementary production amplitude are determined in pseudovector πN coupling and supplied with a form factor. The ∆ resonance is considered both in the s and the u channel. The parameters of the ∆ resonance and the cutoff of the form factors are fixed on the leading photoproduction multipole...
