Physics and methods in meson spectroscopy - Int. Joint Workshop CERN COMPASS-Jefferson Lab-GSI FAIR

Understanding the meson spectrum in the light and heavy quark sectors of QCD remains one of the fundamental objectives of strong interaction physics. Experiments planned at exisiting and future facilities will soon provide extensive data on meson production with protons and mesonic (CERN COMPASS), polarized photon (Jefferson Lab GlueX) and antiproton beams (GSI FAIR PANDA). New analysis methods are presently being developed in order to make optimal use of these high-statistics data sets and improve the reliability of traditional partial wave analysis. Motivated by the beginning of COMPASS and BESIII data taking, this workshop will summarize recent progress in understanding the physics issues, analysis methods, and instrumentation in meson spectroscopy. Topics include the relation of the meson spectrum to QCD (lattice and non-lattice), new developments in partial wave analysis and related methods, and the advantages of different probes in identifying and studying possible new objects. Particular emphasis will be placed on introducing the analysis methods developed for the different experimental approaches to researchers working in other fields and to develop common strategies.
