Effect of double-polarization data in fits to single-pion photoproduction
arXiv:nucl-th/0212055 · doi:10.1103/PhysRevC.67.048201
Abstract
We investigate the influence of new Jefferson Lab polarization-transfer data, Cx and Cz, and recoil polarization, Py, measurements in multipole fits to the single-pion photoproduction database. Results are compared to those found with the addition of a double-polarization quantity associated with the Gerasimov- Drell-Hearn sum rule.
