Recent and ongoing studies from the A2 Collaboration at MAMI — •Edoardo Mornacchi for the A2 collaboration — Johannes Gutenberg-Universität, Mainz, Germany

The A2 Collaboration at the Mainz Microtron (MAMI) performs photoproduction experiments to investigate the internal structure of nucleons and mesons, gaining a better understanding of non-perturbative QCD.

It uses a circularly or linearly polarized Bremsstrahlung photon beam with energies up to 1.6 GeV, together with a variety of unpolarized and polarized targets. The resulting particles are then detected using the large acceptance Crystal Ball-TAPS detector system, which is perfectly suited for the detection of multi-photon final states.

An overview of the ongoing studies as well as recent results from the A2 Collaboration will be given, along with an outlook on current and future measurements.
