用QCD求和规则分析标量、轴矢量、矢量、张量双粲四夸克态

Analysis of the scalar, axialvector, vector, tensor doubly charmed tetraquark states with QCD sum rules

Zhi-Gang Wang, Ze-Hui Yan

摘要:

本文构造了轴向矢量-双夸克-轴向矢量-反双夸克型流来插值标量、轴向矢量、矢量、张量双粲四夸克态,并通过对10维真空凝聚体进行一致的算子乘积展开,用QCD求和定则系统地研究了它们的质量,使预测的质量与实验数据相符合.我们可以在粲介子对的Okubo-Zweig-Iizuka超允许强衰变中寻找双粲四夸克态。

英文摘要:

In this article, we construct the axialvector-diquark-axialvector-antidiquark type currents to interpolate the scalar, axialvector, vector, tensor doubly charmed tetraquark states, and study them with QCD sum rules systematically by carrying out the operator product expansion up to the vacuum condensates of dimension 10 in a consistent way, the predicted masses can be confronted to the experimental data in the future. We can search for those doubly charmed tetraquark states in the Okubo-Zweig-Iizuka super-allowed strong decays to the charmed meson pairs.
