Abstract

In this paper magnetic dipole moment form factor, G(M)((2))(Q(2)), describing the radial excitation of decuplet baryons to octet baryons electromagnetic transitions as well as the ratios, RSM = - 1/4m(2)(2) root 4(m2)(Q)(2)(2) + (m(2)(2) - Q(2) - m(1)(2))2 G(C)((2))(Q(2))/ G(M)((2))(Q(2)) and R-EM = -G(E)((2))(Q(2)) G(M)((2))(Q(2)) are calculated in the framework of light-cone sum rules. We also estimate the degree of the violation of U-spin symmetry.
