Hyperon magnetic moments in SU(3)

Abstract

The hyperon magnetic moments and the magnetic transition moment $\mu _{\Sigma _{}^0{}_{\Lambda }{}^{}}^{}{}_{}{}^{}$ have been calculated under various assumptions for the electromagnetic current operator within the spectrum-generating SU(3) approach. None of these assumptions, including the conventional ones using the Gell-Mann-Nishijima formula and SU(3) symmetry, lead to an acceptable fit to the experimental data.
