Functional reduction of the S matrix in the canonical formalism
Mark W. Paris
The Low equation is derived in a functional approach to the reduction of the S matrix in the canonical formalism. This establishes the vacuum expectation value of the scattering ma…
Effect of Sigma-beam Asymmetry Data on Fits to Single Pion Photoproduction off Neutron
I. I. Strakovsky, R. A. Arndt, W. J. Briscoe +2
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 th…
Comparing partial-wave amplitude parametrization with dynamical models of meson-nucleon scattering
Mark W. Paris, Ron L. Workman
Relationships between partial-wave amplitude parametrizations, in particular the Chew-Mandelstam approach, and dynamical coupled-channel models are established and investigated. A…
Model dependence of single-energy fits to pion photoproduction data
Ron L. Workman, Mark W. Paris, William J. Briscoe +4
Model dependence of multipole analysis has been explored through energy-dependent and single-energy fits to pion photoproduction data. The MAID energy-dependent solution has been u…
