Unitarization of Koerner-Kuroda model of electromagnetic structure of octet 1/2{sup +} baryons

Technical Report:

Abstract

The Koerner-Kuroda model of the electromagnetic structure of octet 1/2{sup +} baryons is restored on a more topical physical basis. Electromagnetic radii of baryons under consideration are calculated and compared with other model predictions. By an incorporation of a two-cut approximation of correct form factor analytic properties and nonzero vector-meson widths, the Koerner-Kuroda model is unitarized, providing in this manner imaginary parts of the octet 1/2{sup +} baryon form factors to be nonzero just starting from a branch point corresponding to the lowest threshold. (author). 32 refs, 16 figs, 2 tabs.
