Abstract:
This volume brings together experts on the quark-gluon structure of matter as it applies to nucleon resonance physics. The contributions discuss the latest findings in areas such as meson production via electromagnetic and hadronic reactions, baryon resonance structure in chiral and lattice QCD approaches, and the extraction of resonance parameters from coupled-channels analysis of data. Contents: MAID Analysis Technique (L Tiator); Results from the GDH Experiment at Mainz and Bonn (A Braghieri); The Crystal Ball at MAMI (D Watts); Dynamically Generated Baryon Resonances (M Lutz); Progress Report for a New Karlsruhe-Helsinki Type Pion-Nucleon Partial Wave Analysis (S Watson); A Genetic Algorithm Analysis of N ∗ Resonances (D G Ireland); Eta Photoproduction of the Neutron at GRAAL (V Kuznetsov); The Problem of Exotic States: View from Complex Angular Momenta (Ya Azimov); Excited Baryons in the 1/ N c Expansion (N Matagne); and other papers. Readership: Researchers in nuclear, high-energy and particle physics.
