QCD求和规则中的轻标量介子

Light Scalar Mesons in the QCD Sum Rule

Hua-Xing Chen, Atsushi Hosaka, Shi-Lin Zhu

摘要:

我们在QCD求和规则下研究了轻标量介子。我们发现在定域形式中存在五个独立的标量四夸克流,并利用这些流及其组合进行了QCD求和规则分析。与传统的\bar{q} q流求和规则相比,我们的结果支持低位标量介子的四夸克结构。

英文摘要:

We study the light scalar mesons in the QCD sum rule. We find that there are five independent scalar tetraquark currents in the local form, and we perform QCD sum rule analysis using both these currents and their combinations. Compared with the sum rules by conventional \bar{q} q currents, our result supports a tetraquark structure for low-lying scalar mesons.
