Beam-helicity asymmetries ; charged pions and the decay photon

Sažetak
Beam-helicity asymmetries have been measured at the MAMI accelerator in Mainz in the three isospin channels gama p--->pi+ pi0n, gamma p---> pi0 p0 p, and gamma p--->pi+ pi-p. The circularly polarized photons, produced from bremsstrahlung of longitudinally polarized electrons, were tagged with the Glasgow magnetic spectrometer. Charged pions and the decay photons of pi0 mesons were detected in a 4pi electromagnetic calorimeter which combined the Crystal Ball detector with the TAPS detector. The precisely measured asymmetries are very sensitive to details of the production processes and are thus key observables in the modeling of the reaction dynamics.
