Polarized correlations while the photoproduction of pion-pairs on proton

The authors investigate the photoproduction of a pion pair on a polarized target with circular-polarized photon beams. It is suggested that as the energy of the incident photons increases, maximum asymmetry in the area of small angles occurs less frequently, while the minimum polarization of the recoil proton shifts towards the small angles. A detailed diagram is given. The investigation is based on a model proposed by the authors. (author)
