Glueballs, Hybrids, Multiquarks. Experimental facts versus QCD inspired concepts
Eberhard Klempt, Alexander Zaitsev
The spectroscopy of light and heavy mesons is reviewed with emphasis on glueballs, hybrids, and tetraquarks.
Further evidence for N(1900)P_{13} from photoproduction of hyperons
V. A. Nikonov, A. V. Anisovich, E. Klempt +2
We report further evidence for from an analysis of a large variety of photo- and pion-induced reactions, in particular from the new CLAS measurements of double pola…
Baryon resonances and polarization transfer in hyperon photoproduction
A. V. Anisovich, V. Kleber, E. Klempt +3
A partial wave analysis is presented of data on photoproduction of hyperons including single and double polarization observables. The large spin transfer probability reported by th…
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…
Baryon-baryon and baryon-antibaryon interaction amplitudes in the spin--momentum operator expansion method
A. V. Anisovich, V. V. Anisovich, E. Klempt +2
Partial wave scattering amplitudes in baryon-baryon and baryon-antibaryon collisions and amplitudes for the production and decay of baryon resonances are constructed in the framewo…
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…
