Diquark correlations in baryon spectroscopy and holographic QCD

Hilmar Forkel, Eberhard Klempt

We introduce an improved mass formula for the nucleon and delta resonances and show how it emerges from AdS/QCD in a straightforward extension of the 'metric soft wall' gravity dua…

Photoproduction of eta-mesons off nuclei for Eg < 2.2 GeV

T. Mertens, I. Jaegle, P. Muehlich +69

Photoproduction of mesons off C, Ca, Nb, and Pb nuclei has been measured with a tagged photon beam with energies between 0.6 and 2.2 GeV. The exper…

Linearly polarised photon beams at ELSA and measurement of the beam asymmetry in pi^0-photoproduction off the proton

D. Elsner, B. Bantes, O. Bartholomy +55

At the electron accelerator ELSA a linearly polarised tagged photon beam is produced by coherent bremsstrahlung off a diamond crystal. Orientation and energy range of the linear po…

Photoproduction of mesons off neutrons from a deuteron target

A. V. Anisovich, I. Jaegle, E. Klempt +4

A formalism is developed for the partial wave analysis of data on meson photoproduction off deuterons and applied to photoproduction of and mesons. Different interpretati…

Delta resonances, quark models, chiral symmetry and AdS/QCD

E. Klempt

The mass spectrum of Delta resonances is compared to predictions based on three quark-model variants, to predictions assuming that chiral symmetry is restored in high-mass baryon r…

Study of the reaction

I. Horn

The reaction has been studied with the CBELSA detector at the tagged photon beam of the Bonn electron stretcher facility. The reaction shows contributions from $Δ^+(1…
