Hadron structure at small momentum transfer
Thomas Walcher
Giving three examples, the form factors of the nucleon, the polarisability of the charged pion and the interference of the with the excitation of the…
Beam-helicity asymmetry in photon and pion electroproduction in the Delta(1232) resonance region at Q^2= 0.35 (GeV/c)^2
A1 Collaboration, I. K. Bensafa, P. Achenbach +40
The beam-helicity asymmetry has been measured simultaneously for the reactions (e p \to e p γ) and (e p \to e p π^0) in the resonance region at 0.35 (GeV/c). T…
Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena
M. J. Amarian, V. M. Braun, S. J. Brodsky +28
These are the mini-proceedings of the workshop ``Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena" held at the Physikzentrum Bad Honnef from July 15 to 19, 2002. Every a…
A simple model to explain narrow nucleon resonances below the πN threshold
Thomas Walcher
Several experiments suggest the existence of narrow excited states in the nucleon below the πN threshold. Taking all information together a series of states emerges at masses of 94…
