Photon decay rate of sigma plus from unsubtracted dispersion relations
Taking the viewpoint of unsubtracted dispersion relations we derive integral representations for the weak photon decay amplitudes Fl and F2. The integrals involve the magnetic and electric dipole amplitudes M and .1 Eo+ of the photopion production. They also involve the pion-nucleon scattering …

An integral equation for the anomalous deuteron vertex and a comparison of two normalization conditions
… of an eigenvalue con= \ dition exists if unsubtracted dispersion relations are postulatedo The anomalous region is treated by means of a modification of the Nishijima continuation procedure. The equations are derived in a one pion model to illustrate the method. A partial diagrammatic …
