The effect of the {Delta} excitation on proton-proton bremsstrahlung
- Institute of Theroretical Physics, Juelich (Germany)
The proton-proton bremsstrahlung is investigated with a coupled-channel model with {pi} and {Delta} degrees of freedom. The model is consistent with the NN scattering up to 1 GeV and the {gamma}N{Delta} vertex determined in the study of pion photoproduction on the nucleon. We find that the {Delta} excitation can significantly improve the agreement with the pp {yields} pp{gamma} data at E{sub L} = 280 MeV. The N{Delta} rescattering plays an important role in determining the angular distribution and analyzing powers. Predictions at E{sub L} = 550 and 800 MeV were made for the forthcoming experimental tests at COSY of Juelich. A paper describing our results was submitted for publication.
