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


Abstract in English

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