Magnetic Moments of the Strange Baryons and the Algebra of Currents

Using equal-time commutation relations of the axial-vector "charges" with the isoscalar and isovector electromagnetic current densities, the magnetic moments of the strange members of the baryon octet and the ${\ensuremath{\Sigma}}^{0}\ensuremath{-}\ensuremath{\Lambda}$ transition moment have been calculated in terms of the pseudoscalar-meson photoproduction amplitudes, which are evaluated using low-lying baryon resonant states. The results agree very well with the experimental values available for the ${\ensuremath{\Sigma}}^{+}$ and the $\ensuremath{\Lambda}$ magnetic moments. A comparison is also made with the results of the $\mathrm{SU}(3)$ symmetry.
