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

摘要

The method of QCD sum rules in the presence of external elctromagnetic fields is used to calculate the Ω\Omega magnetic moment μΩ\mu_{\Omega^-} and Σ0\Sigma^0-Λ\Lambda transition magnetic moment μΣ0Λ\mu_{\Sigma^0\Lambda}, with the susceptibilities obtained previously from the study of octet baryon magnetic moments. The results μΩ=1.92μN\mu_{\Omega^-}=-1.92\mu_N and μΣ0Λ=1.5μN\mu_{\Sigma^0\Lambda}=1.5\mu_N are in good agreement with the recent experimental data.
