Evidence for a parity doublet Delta(1920)P_{33} and Delta(1940)D_{33}$ from γp\to pπ^0η
I. Horn
Evidence is reported for the existence of a parity doublet of Delta resonances with total angular momentum J=3/2 from photoproduction of the p pi^0 eta final state. The two parity…
Photoproduction of pi0-mesons off protons from the Delta(1232) region to E(gamma) = 3 GeV
H. van Pee, O. Bartholomy, V. Crede
Photoproduction of pi0 mesons was studied with the Crystal-Barrel detector at ELSA for incident energies from 300 MeV to 3 GeV. Differential cross sections d sigma /d Omega, d sigm…
Photoproduction of pi0 omega off protons for E(gamma) < 3 GeV
J. Junkersfeld
Differential and total cross-sections for photoproduction of gamma proton to proton pi0 omega and gamma proton to Delta+ omega were determined from measurements of the CB-ELSA expe…
Nucleon resonance decay by the channel
R. Castelijns et al.
Hyperon production off the proton in the channel has been studied at the tagged photon beam facility at the ELSA electron accelerator in Bonn. This experiment was part of…
Measurement of the beam asymmetry in eta-photoproduction off the proton
D. Elsner et al.
The beam asymmetry, , was measured at ELSA in the reaction using linearly polarised tagged photon beams, produced by coherent bremsstrahlung off a diamond. The…
