Analysis of ${\Omega }_b^{-}(bss)$ and ${\Omega }_c^0(css)$ with QCD sum rules

Abstract

In this article, we calculate the masses and the pole residues of the ${1/2}^{+}$ heavy baryons ${\Omega }_c^0(css)$ and ${\Omega }_b^{-}(bss)$ with the QCD sum rules. The numerical values $M_{{\Omega }_c^0}=(2.72\pm 0.18)\mathrm{GeV}$ (or $M_{{\Omega }_c^0}=(2.71\pm 0.18)\mathrm{GeV}$) and $M_{{\Omega }_b^{-}}=(6.13\pm 0.12)\mathrm{GeV}$ (or $M_{{\Omega }_b^{-}}=(6.18\pm 0.13)\mathrm{GeV}$) are in good agreement with the experimental data.
