CDD Effects in Partial Wave Dispersion Relations and the Dynamical Calculation of Resonances
An almost overwhelming number of resonances are now known to exist. In the pion-nucleon system alone, recent phase shift analyses have revealed a total of 19 resonances at masses up to 2200 MeV,1 and the situation is further complicated by the fact that more than one resonance occurs in some partial waves. An important problem in strong interaction physics is to understand the dynamical origin of these resonances.
