QCD sum rules are used to calculate the contribution of short-distancesingle-quark transition $s\rightarrow d \gamma$, to the amplitudes of thehyperon radiative decay, $\Omega^-\rightarrow \Xi^-\gamma$. We re-evaluate theWilson coefficient of the effective operator responsible for this transition.We obtain a branching ratio which is comparable to the unitarity limit.Comment: 15 pages, Revtex, 13 figures available as a uuencoded, gz-compressed  ps fil
