Search for the Charmed Baryonium and Dibaryon Structures via the QCD Sum Rules

Abstract

In the present work, we construct eight six-quark currents to study the ${\Sigma }_c{\overline{\Sigma }}_c$ baryonium and ${\Sigma }_c{\Sigma }_c$ dibaryon states via the QCD sum rules. For either ${\Sigma }_c{\overline{\Sigma }}_c$ baryonium or ${\Sigma }_c{\Sigma }_c$ dibaryon states, we construct four currents with the $J^P=1^{-},1^{+},0^{+}$ and $0^{-}$ . Except the current $1^{+}$ of ${\Sigma }_c{\Sigma }_c$ , we find the Borel windows for the other seven. There are two possible ${\Sigma }_c{\overline{\Sigma }}_c$ molecular states or compact six-quark states with the $J^P=1^{-}$ and $0^{-}$ . The results of the current $0^{+}$ of ${\Sigma }_c{\Sigma }_c$

用QCD求和规则寻找魅力重子和二重子结构

在本工作中，我们构造了八个六夸克流来研究∑c∑c重子和∑通过QCD和的c∑c二核态规则。对于∑c∑？c钡鎓或∑c∑c二核态，我们构造了四个电流，其中J P=1−，1+，0+和0−。除了当前的1+∑c，我们找到了其他七个的Borel窗口。
