| Description/Abstract | Two-pion photoproduction in the reaction {rvec {gamma}}p {yields} p{pi}{sup +}{pi}{sup -} 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. Beam-helicity-dependent angular distributions of the final-state particles were measured. The large cross-section asymmetries that have been found exhibit strong sensitivity to the kinematics of the reaction, and are compared with preliminary model calculations by Mokeev and Roberts. |
