Ω−→ΛK−γand theΩ−magnetic moment

We analyze the possibility that the decay ${\Omega }^{-}\to \Lambda K^{-}\gamma$ can be used as an alternative experimental procedure to determine the ${\Omega }^{-}$ magnetic moment. Using the soft-photon approximation we derive a model-independent expression for the angular and energy distribution of photons. We find that this observable is sensitive to the ${\Omega }^{-}$ magnetic moment when photons and kaons are emitted collinearly.
