Analysis of the $1/2^{-}$ and $3/2^{-}$ heavy and doubly heavy baryon states with QCD sum rules

Abstract

In this article, we study the $(1/2{)}^{-}$ and $(3/2{)}^{-}$ heavy and doubly heavy baryon states ${\Sigma }_Q((1/2{)}^{-})$, ${\Xi }_Q^{\prime }((1/2{)}^{-})$, ${\Omega }_Q((1/2{)}^{-})$, ${\Xi }_{QQ}((1/2{)}^{-})$, ${\Omega }_{QQ}((1/2{)}^{-})$, ${\Sigma }_Q^{\ast }((3/2{)}^{-})$, ${\Xi }_Q^{\ast }((3/2{)}^{-})$, ${\Omega }_Q^{\ast }((3/2{)}^{-})$, ${\Xi }_{QQ}^{\ast }((3/2{)}^{-})$ and ${\Omega }_{QQ}^{\ast }((3/2{)}^{-})$ by subtracting the contributions from the corresponding ${\frac{1}{2}}^{+}$ and ${\frac{3}{2}}^{+}$ heavy and doubly heavy baryon states with the QCD sum rules in a systematic way, and make reasonable predictions for their masses.
