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,…
First Measurement of the Double Spin Asymmetry in in the Resonance Region
CLAS Collaboration, R. De Vita
The double spin asymmetry in the reaction has been measured for the first time in the resonance region for four-momentum transfer GeV$^2…
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…
Charge-Symmetry Violation in Pion Scattering from Three-Body Nuclei
A. E. Kudryavtsev, V. E. Tarasov, B. L. Berman +3
We discuss the experimental and theoretical status of charge-symmetry violation (CSV) in the elastic scattering of pi+ and pi- on 3H and 3He. Analysis of the experimental data for…
Observation of exclusive DVCS in polarized electron beam asymmetry measurements
CLAS Collaboration, S. Stepanyan
We report the first results of the beam spin asymmetry measured in the reaction e + p -> e + p + gamma at a beam energy of 4.25 GeV. A large asymmetry with a sin(phi) modulation is…
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…
Precision Pion-Proton Elastic Differential Cross Sections at Energies Spanning the Delta Resonance
M. M. Pavan, J. T. Brack, F. Duncan +15
A precision measurement of absolute pi+p and pi-p elastic differential cross sections at incident pion laboratory kinetic energies from T_pi= 141.15 to 267.3 MeV is described. Data…
