Absolute Total np and pp Cross Section Determinations
R. A. Arndt, W. J. Briscoe, A. B. Laptev +2
Absolute total cross sections for np and pp scattering below 1000 MeV are determined based on partial-wave analyses of NN scattering data. These cross sections are compared with mo…
Production of Pseudoscalar Mesons
W. J. Briscoe, R. A. Arndt, I. I. Strakovsky +1
Experiments that study the hadronic and electromagnetic production of the pseudoscalar mesons -- pions, etas and kaons, contribute to our knowledge of the properties of baryon and…
Effect of double-polarization data in fits to single-pion photoproduction
R. A. Arndt, I. I. Strakovsky, R. L. Workman
We investigate the influence of new Jefferson Lab polarization-transfer data, Cx and Cz, and recoil polarization, Py, measurements in multipole fits to the single-pion photoproduct…
Analysis of Pion Photoproduction Data
R. A. Arndt, W. J. Briscoe, I. I. Strakovsky +1
A partial-wave analysis of single-pion photoproduction data has been completed. This study extends from threshold to 2 GeV in the laboratory photon energy, focusing mainly on the i…
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…
Pole versus Breit-Wigner resonance description of the orbitally excited baryons
R. L. Workman
We consider the masses used in recent studies involving the nonstrange sector of the l=1 baryons. The use of T-matrix and K-matrix poles versus the conventional Breit-Wigner masses…
