Vector meson dominance and radiative decays of heavy spin-3/2 baryons to heavy spin--1/2 baryons

Abstract

Using the calculated values of the strong coupling constants of the heavy sextet spin-3/2 baryons to sextet and antitriplet heavy spin-1/2 baryons with light mesons within the light cone QCD sum rules method, and vector meson dominance assumption, the radiative decay widths are calculated. These widths are compared with the "direct" radiative decay widths predicted in the framework of the light cone QCD sum rules.Comment: 8 pages, no figures, LaTeX formatte
