Hadron Archive Data Repository Online Project (HADRO-project) The aim of this project is to set up a publicly accessible database to archive The full range of data on cross-sections and polarization asymmetries measured in hadro and photo-production of baryon resonances For each N* its mass, width, and couplings as determined by the positions and residues of their poles in the complex energy plane Transition form-factors for excited N*’s as a function of photon momentum For each analysis, the partial wave amplitudes in which these excited baryons occur A graphical representation of the data A graphical comparison of the partial waves in each analysis A detailed exposition of the methods used in each analysis Where appropriate these will be compared with the detailed predictions of QCD. Step 1 is above, step 2 is extension to mesons International Advisory Board Curtis Meyer (CMU) Berndt Mueller (Duke) David Richards (JLab) Michael Pennington (JLab) March 18, 2011

PDG 1971 Rittenberg et al. after discussing Breit-Wigner fits to 33 phase-shift We conclude that the mass and width of (1236) are in a state of flux; Therefore we do not quote any errors in the table. PDG 1972 Barbaro-Galtieri et al. ? PDG 1973 Lasinski et al. Comment on the Mass and Width of (1236) In our last edition, we presented an exhaustive discussion of the relative uniqueness of the pole position. On the basis of that study we have entered the pole position in both the Table and Data Card Listings.
