Magnetic Moments of theΛandΣHyperons

A relation among the magnetic moments of ${\Sigma }^{+}$, ${\Sigma }^0$, ${\Sigma }^{-}$, and $\Lambda$ is obtained as a consequence of the proposed symmetries of strong interactions, a minimal electromagnetic coupling for the electromagnetic interactions being assumed. The magnetic moments of the $\Lambda$ and $\Sigma$ hyperons are calculated with the aid of mass spectral representations in which only the contributions of the bound states are taken into account. The present calculation of these magnetic moments are compared with various other calculations. Remarks are made on the possible experimental values.
