Beam asymmetry in near threshold omega photoproduction off the proton

Frank Klein et al.

The photoproduction of omega mesons off protons has been studied at the Bonn ELSA accelerator from threshold to E_gamma = 1700 MeV. Linearly polarized beams were produced via coher…

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…

N* and Delta* decays into N pi0 pi0

U. Thoma, M. Fuchs, A. V. Anisovich +45

Decays of baryon resonances in the second and the third resonance region into N pi0 pi0 are studied by photoproduction of two neutral pions off protons. Partial decay widths of N*…

New results on the Roper resonance and the P_{11} partial wave

A. V. Sarantsev

Properties of the Roper resonance, the first scalar excitation of the nucleon, are determined. Pole positions and residues of the partial wave are studied in a combined an…

Evidence for the positive-strangeness pentaquark in photoproduction with the SAPHIR detector at ELSA

The SAPHIR Collaboration, J. Barth

The positive--strangeness baryon resonance is observed in photoproduction of the final state with the SAPHIR detector at the Bonn ELectron Stretcher Accelerat…

First measurement of the Gerasimov-Drell-Hearn integral for Hydrogen from 200 to 800 MeV

GDH-Collaboration, A2-Collaboration, : +1

A direct measurement of the helicity dependence of the total photoabsorption cross section on the proton was carried out at MAMI (Mainz) in the energy range 200 < E_gamma < 800 MeV…
