New Result for the Pion-Nucleon Sigma Term from an Updated VPI/GW Pion-Nucleon Partial-Wave and Dispersion Relation Analysis
M. M. Pavan, R. A. Arndt, I. I Strakovsky +1
A new result for the nucleon sigma term from an updated pion-nucleon partial-wave and dispersion relation analysis of the Virginia Polytechnic Institute (now George Washington Univ…
Extraction of the D13(1520) photon-decay couplings from pion- and eta-photoproduction data
R. L. Workman, R. A. Arndt, I. I. Strakovsky
We compare results for the D13(1520) photon-decay amplitudes determined in analyses of eta- and pion-photoproduction data. The ratio of helicity amplitudes (A_3/2 / A_1/2), determi…
Determination of the Pion-Nucleon Coupling Constant in the VPI/GW Pion-Nucleon Elastic Scattering Partial Wave and Dispersion Relation Analyis
M. M. Pavan, R. A. Arndt, I. I. Strakovsky +1
Our extraction of the pion-nucleon coupling constant from πp elastic scattering data is outlined. A partial wave analysis (T_π < 2100 MeV) is performed simultaneously with a fixed-…
Charge Symmetry Violation Effects in Pion Scattering off the Deuteron
V. V. Baru, A. E. Kudryavtsev, V. E. Tarasov +3
We discuss the theoretical and experimental situations for charge symmetry violation (CSV) effects in the elastic scattering of pi+ and pi- on deuterium (D) and 3He/3H. Accurate co…
Sensitivity to the pion-nucleon coupling constant in partial-wave analyses of elastic pi-N and NN scattering and pion photoproduction
R. A. Arndt, I. I. Strakovsky, R. L. Workman +1
We summarize results obtained in our studies of the pion-nucleon coupling constant. Several different techniques have been applied to pi-N and NN elastic scattering data, and the e…
Inclusive and exclusive photoproduction on the deuteron: - and -threshold phenomena
H. Yamamura, K. Miyagawa, T. Mart +2
Inclusive and exclusive photoproduction on the deuteron are investigated theoretically. Modern hyperon-nucleon forces and a recently updated kaon photoproduction opera…
