摘要:

本文利用QCD求和规则,系统地研究了${(1/2)^-}$和${(3/2)^-}$重子态和二重重子态$Σ_Q({(1/2)^-})$,$Ξ'_Q({(1/2)^-})$,$Ω_Q({(1/2)^-})$,$Ξ_{QQ}({(1/2)^-})$,$Ω_{QQ}({(1/2)^-})$,$Σ_Q^*({(3/2)^-})$,$Ξ_Q^*({(3/2)^-})$,$Ω_Q^*({(3/2)^-})$,$Ξ^*_{QQ}({(3/2)^-})$和$Ω^*_{QQ}({(3/2)^-})$,并对它们的质量进行了合理的预测.

英文摘要:

In this article, we study the ${(1/2)^-}$ and ${(3/2)^-}$ heavy and doubly heavy baryon states $Σ_Q({(1/2)^-})$, $Ξ'_Q({(1/2)^-})$, $Ω_Q({(1/2)^-})$, $Ξ_{QQ}({(1/2)^-})$, $Ω_{QQ}({(1/2)^-})$, $Σ_Q^*({(3/2)^-})$, $Ξ_Q^*({(3/2)^-})$, $Ω_Q^*({(3/2)^-})$, $Ξ^*_{QQ}({(3/2)^-})$ and $Ω^*_{QQ}({(3/2)^-})$ by subtracting the contributions from the corresponding ${1\over 2}^+$ and ${3\over 2}^+$ heavy and doubly heavy baryon states with the QCD sum rules in a systematic way, and make reasonable predictions for their masses.
