论文摘要
在本文中，我们研究了AxialVector-Diquark-AxialDiquark（$ aa $）类型和标量 - diquark-scalar-antidiquark（$ ss $）类型完全开放的味道$ CS \ bar {u} \ bar {u} \ bar {d} $ tetraquark anctra $ tetraquark ancts spin-pary $ j^p = par pary $ j^p = $ ulul预测的群众$ m_ {aa} = 2.91 \ pm0.12 \，\ rm {gev} $和$ m_ {ss} = 3.05 \ pm0.10 \，\ rm {gev} $ cs \ bar {u} \ bar {d} $ tetraquark state。
In this article, we study the axialvector-diquark-axialvector-antidiquark ($AA$) type and scalar-diquark-scalar-antidiquark ($SS$) type fully open flavor $cs\bar{u}\bar{d}$ tetraquark states with the spin-parity $J^P={0}^+$ via the QCD sum rules. The predicted masses $M_{AA}=2.91\pm0.12\,\rm{GeV}$ and $M_{SS}=3.05\pm0.10\,\rm{GeV}$ support assigning the $X_0(2900)$ to be the $AA$-type scalar $cs\bar{u}\bar{d}$ tetraquark state.
