Quasi-free photoproduction of eta-mesons off 3He nuclei
L. Witthauer, D. Werthmueller, I. Keshelashvili +70
Quasi-free photoproduction of -mesons has been measured off nucleons bound in He nuclei for incident photon energies from the threshold region up to 1.4 GeV. The experiment…

C. M. Tarbert, D. P. Watts, D. I. Glazier +57
Information on the size and shape of the neutron skin on Pb has been extracted from coherent pion photoproduction cross sections measured using the Crystal Ball together wi…
Beam asymmetry for pi+ and pi0 photoproduction on the proton for photon energies from 1.102 to 1.862 GeV
M. Dugger, B. G. Ritchie, P. Collins +5
Beam asymmetries for the reactions gamma p -> p pi0 and gamma p -> n pi+ have been measured with the CEBAF Large Acceptance Spectrometer (CLAS) and a tagged, linearly polarized pho…
First Observation of the Line Shape in Electroproduction
H. Y. Lu, R. A. Schumacher, CLAS Collaboration
We report the first observation of the line shape of the from electroproduction, and show that it is not a simple Breit-Wigner resonance. Electroproduction of $K^+ Λ(1405…
Demonstration of a novel technique to measure two-photon exchange effects in elastic scattering
M. Moteabbed, M. Niroula, B. A. Raue +147
The discrepancy between proton electromagnetic form factors extracted using unpolarized and polarized scattering data is believed to be a consequence of two-photon exchange (TPE) e…
