Established to study the extraction and interpretation of resonance parameters within different approaches. Important questions addressed are: How must one separate background from resonance contributions? How do we compare extracted resonance parameters with quark model results? What minimum theoretical requirements should different approaches include?

Working Group Members

Established to study the model-dependence of partial-wave (multipole) analyses of data associated with the N^* program. The ultimate goal is a set of PWA which are as model-independent as possible. An associated issue is the choice of an optimum set of experiments necessary to achieve this goal.

Benchmark Data/Analyses for Pion Photoproduction on the Proton

Established to explore and advance database issues related to N^* physics. The ideal BRAG database would be one containing all experimental data below W = 3 GeV and Q² = 5 GeV² using electromagnetic (photon and electron) with hadron (pion, kaon, and proton) probes with hydrogen and deuterium targets. Building upon the current SAID site at GW (with about 200k data: pion photo- and electroproduction; eta and kaon photoproduction; piN-->piN, 2piN; K^±N; NN-->NN, pid-->pid, pp) a new four-year project with the objective of creating a new web-based database and information management system, called iSAID, is under construction.
