Measurement of double polarisation asymmetries in -photoproduction
H. Eberhardt, T. C. Jude, H. Schmieden +72
The first measurements of the beam-target-helicity-asymmetries and in the photoproduction of -mesons off protons at the CBELSA/TAPS experiment are reported. () w…
High statistics study of the reaction
V. Sokhoyan, E. Gutz, V. Crede +62
The photoproduction of 2 mesons off protons was studied with the Crystal Barrel/TAPS experiment at the electron accelerator ELSA in Bonn. The energy of photons produced in a…
Hard Two-Photon Contribution to Elastic Lepton-Proton Scattering: Determined by the OLYMPUS Experiment
B. S. Henderson, L. D. Ice, D. Khaneft +67
The OLYMPUS collaboration reports on a precision measurement of the positron-proton to electron-proton elastic cross section ratio, , a direct measure of the contribution…
First measurement of the helicity asymmetry for in the resonance region
M. Gottschall, A. V. Anisovich, B. Bantes +64
The first measurement of the helicity dependence of the photoproduction cross section of single neutral pions off protons is reported for photon energies from 600 to 2300\,MeV, cov…
The N(1520) 3/2- helicity amplitudes from an energy-independent multipole analysis based on new polarization data on photoproduction of neutral pions
J. Hartmann, H. Dutz, A. V. Anisovich +74
New data on the polarization observables T, P, and H for the reaction are reported. The results are extracted from azimuthal asymmetries when a transversely polariz…
Double-polarization observable G in neutral-pion photoproduction off the proton
A. Thiel, H. Eberhardt, M. Lang +69
This paper reports on a measurement of the double-polarization observable G in photoproduction off the proton using the CBELSA/TAPS experiment at the ELSA accelerator in Bon…
