New Analyses of Anomalous Imaginary Part

· Progress of Theoretical Physics (Kyoto)
Using a method of analytic continuation and parameter integration, the anomalous imaginary part of the scattering amplitude is written explicitly with the absorptive part of the matrix element that connects the initial or final state with the intermediate state. The meaning of the intermediate state is clarified. In the case of pion-deuteron scattering, all the singularities are determined. These singularities agree with those obtained by performing a direct parameter integration on the fourth order diagram.
