The pion-nucleon Sigma term is definitely large: results from a G.W.U. analysis of pion nucleon scattering data
M. M. Pavan, I. I. Strakovsky, R. L. Workman +1
A new result for the pion nucleon Sigma term from a George Washington University/TRIUMF group analysis of pion nucleon data is presented. The value Sigma=797 MeV was obtained,…
Analysis of Pion Electroproduction Data
R. A. Arndt, I. I. Strakovsky, R. L. Workman
A fit to the existing pion electroproduction data is presented. This work builds upon our previous analyses of pion photoproduction and elastic pion-nucleon scattering over the Del…
Multipole Analysis of a Benchmark Data Set for Pion Photoproduction
R. A. Arndt, I. Aznauryan, R. M. Davidson +8
We have fitted low- and medium-energy benchmark datasets employing methods used in the MAID/SAID and dynamical model analyses. Independent fits from the Mainz, RPI, Yerevan, and Kh…
Update on Partial-Wave Analysis
Ron Workman
Partial-wave analysis is one step in a process connecting experimental measurements to the N* states we are studying. Progress has been made in the area of `model-independent' anal…
Effect of form factors in fits to photoproduction data
R. M. Davidson, Ron Workman
We compare the effects of several form factor recipes in fits to pseudoscalar meson photoproduction data. The specific examples of pion and kaon photoproduction are used to illustr…
Form factors and photoproduction amplitudes
R. M. Davidson, Ron Workman
We examine the use of phenomenological form factors in tree level amplitudes for meson photoproduction. Two common recipes are shown to be fundamentally incorrect. An alternate for…
