Problems with Extraction of the Nucleon to Delta(1232) Photonic Amplitudes
R. M. Davidson, Nimai C. Mukhopadhyay, M. S. Pierce +3
We investigate the model dependence and the importance of choice of database in extracting the {\it physical} nucleon-Delta(1232) electromagnetic transition amplitudes, of interest…
Stability of the E2/M1 ratio at the T-matrix pole
Ron L. Workman, Richard A. Arndt
We show how the stability of the E2/M1 ratio, evaluated at the T-matrix pole, can be understood given a much wider variation at the K-matrix pole.
Elastic scattering analyses and dispersion relation constraints
R. A. Arndt, I. I. Strakovsky, R. L. Workman +1
We present the results of energy-dependent and single-energy partial-wave analyses of pi-N elastic scattering data with laboratory kinetic energies below 2.1 GeV. We have considere…
The energies and residues of the nucleon resonances N(1535) and N(1650)
R. A. Arndt, A. M. Green, R. L. Workman +1
We extract pole positions for the N(1535) and N(1650) resonances using two different models. The positions are determined from fits to different subsets of the existing ,…
