Recent progress in pion photo- and electroproduction analysis
L. Tiator, D. Drechsel, S. Kamalov +1
Pion photo- and electroproduction has been studied at threshold and in the resonance region below W=2GeV. At threshold pi^0 production can be very well explained within a dynamical…
Pion electroproduction on the nucleon and the generalized GDH sum rule
L. Tiator, D. Drechsel, S. S. Kamalov
Results of the recently developed unitary isobar model (MAID) are presented for the spin asymmetries, structure functions and relevant sum rules in the resonance region. The model…
Pion Electroproduction on the Nucleon and the Generalized GDH Sum Rule
L. Tiator, D. Drechsel, S. S. Kamalov
We present predictions for the spin structure functions of the proton and the neutron in the framework of a unitary isobar model for one-pion photo- and electroproduction. Our resu…
Form factors and exclusive processes -- Introduction and Overview
D. Drechsel
Form factors, polarizabilities and excitation spectra are different aspects of many-body structures. These aspects are constrained by sum rules based on general principles like rel…
Observables in Unpolarized and Polarized Virtual Compton Scattering
A. Metz, B. Pasquini, D. Drechsel
Below pion threshold virtual Compton scattering off the nucleon gives access to the generalized electromagnetic polarizabilities. Different theoretical results for the generalized…
General introduction to Compton scattering
D. Drechsel
Real and virtual Compton scattering has been and will be an important tool to study the structure of hadronic systems. We summarize the status of real Compton scattering and give a…
