متن کاملHelicity-dependent Angular Distributions for Double-charged-pion Photoproduction
Two-pion photoproduction in the reaction γp → pπ + π − has been studied at Jeffer-son 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 reac...
متن کاملInsight into the Narrow Structure in η Photoproduction on the Neutron from Helicity-Dependent Cross Sections.
The double polarization observable E and the helicity dependent cross sections σ_{1/2} and σ_{3/2} were measured for η photoproduction from quasifree protons and neutrons. The circularly polarized tagged photon beam of the A2 experiment at the Mainz MAMI accelerator was used in combination with a longitudinally polarized deuterated butanol target. The almost 4π detector setup of the Crystal Bal...
متن کاملHelicity-Dependent Angular Distributions in Double-Charged-Pion Photoproduction
Two-pion photoproduction in the reaction ~γp → pππ 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 stron...
