Description
The spectrum of bound hadronic states is intimately connected with the behavious of QCD at low energies, where the theory in non-perturbative. An overview will be given of the progress in the study of baryon spectroscopy from recent experimental programmes. In particular, a range of photo-production measurements has been carried out, which include the extraction of several polarization observables for different reaction channels. The results so far show that these data are very useful in the search for evidence for new baryon resonances. A survey of the results will be presented, together with the latest phenomenological fits.
