Abstract
Two-pion photoproduction in the reaction γp → pπ +π − has been studied at Jefferson Lab Hall B using a circularly polarized tagged-photon beam in the energy range between 0.6 GeV and 2.3 GeV. Owing to the large angular acceptance of the CLAS detector, complete beam-helicity-dependent angular distributions of the final-state particles were measured. The large cross-section asymmetries exhibit strong sensitivity to the kinematics of the reaction and provide valuable information on the reaction dynamics. Preliminary results are presented.
