Unified Chew-Mandelstam SAID analysis of pion photoproduction data
arXiv:1202.0845 · doi:10.1103/PhysRevC.86.015202
Abstract
A unified description of single-pion photoproduction data, together with pion- and eta-hadroproduction data, has been achieved in a Chew-Mandelstam parametrization which is consistent with unitarity at the two-body level. Energy-dependent and single-energy partial wave analyses of pion photoproduction data have been performed and compared to previous SAID fits and multipoles from the Mainz and Bonn-Gatchina groups.
