Effect of Sigma-beam Asymmetry Data on Fits to Single Pion Photoproduction off Neutron
arXiv:1108.0179 · doi:10.1063/1.3701254
Abstract
We investigate the influence of new GRAAL Sigma-beam asymmetry measurements on the neutron 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 sum rule.
