The $\mathrm{\Omega }$ and ${\mathrm{\Sigma }}^0$-$\mathrm{\Lambda }$ transition magnetic moments in QCD sum rules

The method of QCD sum rules in the presence of external elctromagnetic fields is used to calculate the $\mathrm{\Omega }$ magnetic moment ${\mu }_{{\mathrm{\Omega }}^{-}}$ and ${\mathrm{\Sigma }}^0$-$\mathrm{\Lambda }$ transition magnetic moment ${\mu }_{{\mathrm{\Sigma }}^0\mathrm{\Lambda }}$, with the susceptibilities obtained previously from the study of octet baryon magnetic moments. The results ${\mu }_{{\mathrm{\Omega }}^{-}}=-1.92{\mu }_N$ and ${\mu }_{{\mathrm{\Sigma }}^0\mathrm{\Lambda }}=1.5{\mu }_N$ are in good agreement with the recent experimental data.
