Abstract:
Nuclear Compton scattering and pion photoproduction are powerful tools to precisely determine the nucleon/hadron structure, thus providing very stringent tests for all non-perturbative QCD models.
The different observables accessible using polarized photon beams and/or polarized nucleon targets play an essential role in this experimental research due to their enhanced sensitivity both to the individual resonances and to the deformation of the nucleon ground state caused by an incoming photon.
The present colloquium will give an overview of the wide range of observables that have been measured by the A2@MAMI collaboration at the tagged photon facility of the MAMI-Mainz accelerator for energies ranging from the pion production threshold up to 1.6 GeV.
