Impact of recent data on N* structure

Hadronic resonances


Many modern experiments are posed with the issue of physics interpretation of their data when the theory is complicated. Certainly, experiments studying N* resonances are in this category. This short paper presents examples of interpretation made by inspection of the data, Breit-Wigner analyses, and coupled channels analysis. There are significant advantages to all three, but only a coupled channels analysis can provide the checks needed for a complete analysis. Examples from the S11 and P13 partial waves are discussed.
