چکیده
We present a relativistic calculation of pion scattering, pion pho-toproduction and Compton scattering on the nucleon in the energy region of the ∆-resonance (upto 450 MeV photon lab energy), in a unified framework which obeys the unitarity constraint. It is found that the recent data on the cross section for nucleon Compton scattering determine accurately the parameters of the electromagnetic nucleon–∆ coupling. The calculated pion-photoproduction partial-wave amplitudes agree well with the recent Arndt analysis.

The Giessen Model - Vector Meson Production on the Nucleon in a Coupled Channel Approach
In ref. we developed a unitary gauge invariant effective Lagrangian model including the final states γN , πN , 2πN , ηN , KΛ, and KΣ (ref.) for a simultaneous analysis of all avaible experimental data for photonand pion-induced reactions on the nucleon. In ref. this analysis was extended to K induced reactions. In this paper we discuss an extension of this method to vector meson nucleon final s...
متن کاملPhoton- and pion-nucleon interactions in a unitary and causal effective theory
In recent years photonand pion-nucleon interactions have been successfully used as a quantitative challenge of chiral perturbation theory (χPT), which is a systematic tool to learn about low-energy QCD dynamics [1]. The application of χPT is however limited to the near threshold region. A method to extrapolate χPT results beyond the threshold region using analyticity and unitarity constraints w...
متن کاملCross sections for pentaquark baryon production from protons in reactions induced by hadrons and photons
Using hadronic Lagrangians that include the interaction of pentaquark Q+ baryon with K and N, we evaluate the cross sections for its production from meson-proton, proton-proton, and photon-proton reactions near threshold. With empirical coupling constants and form factors, the predicted cross sections are about 1.5 mb in kaon-proton reactions, 0.1 mb in r-nucleon reactions, 0.05 mb in pion-nucl...
متن کاملElectron and Photon induced Reactions on Nuclei in the Nucleon Resonance Region∗
We calculate total photon-nucleus and electron-nucleus cross sections γA → X, eA → e′X and several cross sections on pion and eta production in nuclei in the energy regime between the first and the third resonance region for photon virtualities Q2 ≤ 1.0 GeV2 within a semi-classical BUU transport model. In both cases we discuss the varying influence of several medium modifications on the cross s...
متن کاملScattering of photons and vector mesons off nucleonsG
To leading order in the baryon density, the properties of vector mesons in nuclear matter are determined by the vectormeson nucleon scattering amplitudes. Since these amplitudes are not directly constrained by data, there are presently large theoretical ambiguities in predictions of the vector-meson spectral densities in nuclear matter. We address this problem by implementing the constraints fr...
